Badlands National Park, SD

We were so inspired by Bert Gildart’s article in the latest Airstream Life (Fall 2009) that we decided on this trip we finally had to make a visit to Badlands National Park.   That’s a big part of why we chose to go west across South Dakota rather than dipping south first. And it has been worth it.

Every fall we come back west and the first taste of the west we usually get is when we drop in on a national park.   It puts us right back into the western mood, and that gets me thinking of desert camping, rodeo events, prickly pear cactus, Rocky Mountains, and brilliant sunny days where you can see to the horizon.   Badlands has had that effect.   Suddenly we’re talking about extending the trip and not returning to Tucson until “later.”   No decisions yet, but now that we’re out here in the crisp fall weather, it seems a shame to head back to home base already.

In the Badlands campground we met up with a couple from the United Kingdom who just bought a 1966 Caravel at P&S Travel Trailer Service and are traveling for six months across the United States with it.   Rather bravely, or insanely, depending on how you look at it, they are doing this with a three-year-old and a four-month old child.   That’s a lot of people in a 17-foot vintage trailer with no gray tank, but they seem to be doing just fine and I applaud their effort. We joined them last night for some tea and then a look at the sunset over the Badlands, which is spectacular.

A note about the campground options here.   Just north of the park by I-90, and south of the park in the tiny village of Interior, are several RV parks with hookups.   These are very convenient to the park itself, so if you want amenities they are the way to go.   We chose the park’s Cedar Pass campground, which has no hookups but does have bathrooms, water, and a dump station for $10 per night plus $1 per dump.   Amazingly, Verizon cell phones work here sometimes, although they don’t in other parts of the park. I’ve chosen to pretend I can’t get online or make phone calls for a couple of days, so we can all relax.   (Posting the blog tonight is the sole exception — because I know a few people are wondering where we are!)

dsc_2379.jpgBadlands National Park is long and narrow, with only one paved road through the park and a handful of short trails.   We were able to hike most of them in half a day, starting with an 8:30 a.m. ranger talk. Most are easy, with no major elevation changes.   The only significant hazard is the unevenness of the terrain.   Even the local prairie rattlesnake is very timid and nearly impossible to spot before it slithers away.

Despite looking rather forbidding, the park is actually full of living creatures.   Once upon a time there were grizzly bears here, but not any more.   There remain: mule deer, bighorn sheep, prairie dogs, black-footed ferrets (nocturnal), ground squirrels, cliff swallows (and many other birds), lots of insects, and other things.   It’s not desolate at all, although it lacks potable water for humans.

The big story of this park is fossils — lots and lots of fossils, and more appearing with every heavy rain.   The Visitor Center has a great exhibit about the geological history of the park, and the rangers hold daily fossil talks.   No dinosaurs, because this part of South Dakota was part of the ocean in the dinosaur era, but they did have one heck of a giant swimming thing that looks like a cross between a T-Rex and an alligator.

dsc_2415.jpgThe park is rapidly eroding (in geologic terms), and in about half a million years they say it will be gone.   So plan your trip soon, and keep an eye out for bones of some giant titanothere sticking out of the clay. I recommend the hikes, if you want to get a good feel for the place.

Stopping in Mitchell for two nights before coming here was definitely the right move.   We waited out some truly lousy weather (50’s, rain, wind) in full-hookup comfort and got a bunch of work done, then arrived here just in time for spectacular fall weather.   (We also got 14.0 MPG on the drive over, now that the horrible headwind is gone.)   It is perfectly gorgeous now, and in a couple more days things will go downhill again, so the timing was perfect.

The only downside of this is that we can only give Badlands just two nights, which is really not enough time to see everything, because we want to get to Devil’s Tower for the weekend.   This is the end of the season in this area and that means ranger talks, guided tours, and evening campground amphitheater talks are becoming scarce.   Those things add a lot of value to the park experience, so we’re going to try to take in as many as we can before it’s time to start migrating south.

Blue Mounds, diesel, and The Corn Palace

dsc_2265.jpgNew Ulm was good for the weekend event celebrating Hermann but disappointing for the lack of German cars.   “Over 100” were projected by one flyer we saw, and in reality eight showed up. Oh well.   We still got to eat bratwurst, listen to traditional music, and watch the battle reenactment. The local paper was headlined, “Romans Will Lose Today — Again.”

We also went back to a used bookstore in town where we’d bought a few books on Friday, and dropped off about a dozen books to free up some shelf space in the Airstream.   That gave us $21.50 in trade credit, and so of course we picked up another eight or ten books.

dsc_2310.jpgAs I promised myself, we are done withe killer long drives, so on Sunday it was a relatively short 130 miles to Blue Mounds State Park in the southwest corner of Minnesota.   Blue Mounds features a bison herd, which wasn’t in evidence when we visited, but our real destination was Pipestone National Monument about 20 miles north.   Eleanor and I visited this park a couple of years ago without Emma and we wanted her to experience it — and of course do the Junior Ranger program, which she did.

dsc_2327.jpgThe campground at Blue Mounds is very nice, although I never did find out what the Blue Mounds were.   For Sunday night entertainment we thought we’d visit the “historic downtown” of the nearby town of Luverne.   Unfortunately it’s one of those rather dead downtowns that are found everywhere in the midwest, and on Sunday night they roll up the sidewalks early.   Entertainment for the evening was limited to “burrito night” in the trailer and a Scooby Doo movie on DVD — and finding diesel fuel.

When we switched to diesel power I knew that we’d face a greater challenge in finding fuel.   That’s OK, because the extended range of the diesel more than makes up for the difference.     We can tow 380 miles, which is over 100 miles further than we could with the Armada. And not towing, our range is 600-650 miles!

What I didn’t know was how tricky fuel stations can make diesel.   There are two types of pumps, for cars and for big rigs.   The big-rig pumps are sometimes labeled “truck diesel” and sometimes the car pumps are labeled “auto diesel” but not always.   The problem here is that the big-rig pumps use a huge nozzle that won’t fit into the car, and which pumps fuel at such a tremendous rate of speed that using it would likely mean a backup in your filler and a giant mess.   When we go to the diesel pumps we have to hunt out the nozzles that will fit. Sometimes the nozzle on only one side is for autos, which can be hard to get to when we have the Airstream in tow

Then there’s the #1 and #2 trick.   This got us in Wausau. Diesel was advertised at $2.62 per gallon, but after I started filling I noticed I was actually getting charged $2.85 per gallon.   Why?   The left diesel pump was subtly labeled “#1” and the right pump was labeled “#2”.   The #2 pump was the cheap one.   Surprise!   (Difference between #1 & #2 diesel.)

Using either fuel is not a problem as long as it is Ultra Low Sulphur Diesel (ULSD), and both were labeled as such.   Across Canada and the US the conversion to ULSD is complete, so this is not a problem anymore, but last I heard there were still stations in Mexico delivering the older formulation of Low Sulphur Diesel (LSD).

In Luverne we learned a new trick.   The station had two diesel pumps, one dispensing “B5”, which is code for fuel that is 5% biodiesel, 95% dinosaur diesel.   I was half-done filling with the B5 before I noticed the little sticker that identified my pump as the biodiesel pump (and 3 cents per gallon more expensive).   Fortunately, Mercedes has rated the engine for B5 fuel.   Still, I’m getting wary of diesel pumps.

This morning we hitched up for another 100 mile drive, this time to Mitchell, South Dakota.   There was some temptation to just plow through to Badlands National Park, which is our next major destination. But that would have been 340 miles of driving, through what turned out to be fairly poor weather.   We were facing a stiff headwind on I-90, which reduced our towing fuel economy to the worst we’ve ever seen with the GL320:   a lowly 11.5 MPG. At Mitchell we gave up and found a campground.   Instead of battling the weather, we’re going to park ourselves here for a couple of nights and work instead.   I’m finalizing articles for the Winter 2009 issue (due out in November), and Emma needs to get hustling on her fourth grade work.   By getting our work done in a couple of intense days, we can all go to Badlands and drop off the grid for a couple of days with clear consciences.

Mitchell is well known for two major attractions:   The Corn Palace, and Cabela’s.   We’ve actually spend a night at the Cabela’s in the past (it even has a dump station, which attracts RVs like flies), but never dropped in to find out what the heck a Corn Palace is.   Turns out it is a sort of civic center/auditorium that is annually re-decorated with murals made of 13 colors of corn on the cob.   It isn’t actually made of corn, which in this climate is definitely a good thing.   A fire at the Palace would be an interesting thing.   You bring the salt, I’ll bring the butter.

The nearby downtown of Mitchell is suffering the fate of so many others, but it is still alive for the moment.   It needs an injection of creativity and boldness if it is to survive. With the Corn Palace nearby, it at least has a chance. I see these places and I think of the differences between the ones that have deteriorated to nothing but trash and decaying buildings, and the ones that are still vibrant (like Burlington VT’s “Church Street Marketplace”), and I realize that often the key is somebody being entrepreneurial and aggressive.   When the old formula doesn’t work anymore, it’s time to invent a new one.   I hope somebody figures that out in Mitchell.

New Ulm, MN

Why New Ulm?   After many hectic days of long drives and one-night stands (camping), it’s time to stop for a few days and regroup.   We could go to any small town within a reasonable day’s drive of Bloomington, as long as it had the basic amenities.   The Mercedes enthusiasts convinced us to head to New Ulm because this weekend is a festival honoring Hermann, the Cheruscan chief who spearheaded the struggle to defend Germanic tribes against the Roman imperial army in 9 A.D.

You see, if Hermann hadn’t successfully repelled the Roman onslaught, instead of driving Audi, BMW, Mercedes-Benz, Porsche, and Volkwagen, car enthusiasts would all be driving FIATs.   At least, that’s the logic behind bringing 100+ German cars here as part of the weekend festival.   And so we picked New Ulm over Austin, MN — the triumph of bratwurst over SPAM.

dsc_2175.jpg

On the way here we paused at Jim’s Apple Farm, a highly visible roadside stand along Rt 169 that features apple bakery items, candies, dozens of different root beers and licorice, and many other things.   It’s a good stop before you disappear into the seemingly endless corn and soybean fields on the way to New Ulm.

img_5215.jpgNew Ulm is a quiet little town of about 13,000 people.   It is regarded, we are told, as “the most German of all Minnesota communities.”   Up on the hill the townspeople have erected a huge monument to Hermann, and he stands atop the monument in statue, larger than life, with his cloak waving in the breeze and his sword triumphantly raised.   For $1.50 you can climb the stairs to the top of the monument and get the best view of New Ulm there is.   Or, for free, you can walk on the grass around the monument and get the second best view of New Ulm.

We’ve set up camp at Flandrau State Park, directly bordering town, on the assumption that cell phones would work there. They do, sort of, but the campground sits in a bowl which inhibits the signal and so calls have to be made standing outside the Airstream.   Our cellular Internet works only intermittently.   This often happens when we camp in state parks, and so I always have a Plan B for getting online.

In this case, Plan B was the Mega Wash laundry about three miles away, near the Super Wal-Mart.   “Free Wireless Internet” said the sign, and so while Eleanor did the wash I parked myself at a table and got a bunch of real work done at broadband speed.   I’m used to seeing signs that say “Broadband Wireless Internet” and then discovering that it doesn’t work or is tediously slow, but the Mega Wash didn’t let me down.

img_5237.jpgNew Ulm has a lot of minor tourist attractions, which we briefly checked out in the late afternoon when work was done.   In addition to Hermann’s monument, there’s “the first free-standing carillon tower in North America” downtown, lots of German restaurants, and Schell’s Brewery (“the 2nd oldest family owned brewery in the US”).

img_5210.jpgThe carillon plays several times daily according to a posted schedule.   It reminds me of the carillon in Frankenmuth MI, but New Ulm is otherwise nothing like Frankenmuth.

Schell’s is worth a stop even if you don’t do the tour.   The tiny brewery features a nice garden with peacocks wandering around, a little visitor center and gift shop, and a beautiful brick mansion (not open to the public, alas).   We arrived too late for a tour but might check it out again today, after we pay homage to Hermann at the festival.

Bloomington, MN

We spent last night parked near a Mercedes dealer, Feldmann Imports, in Bloomington.   One parking lot is pretty much like another, but we were in this particular one because we were the guests of honor at an informal gathering of Mercedes owners from the Twin Cities area.   There is a Mercedes Club of America (MBCA) with local units all over the country, and the leadership of this particular unit got wind that we would be in the area.   So they invited us to join their members to talk about towing with a Mercedes — a rarely discussed subject indeed.

At this point we have 10,000 miles on the GL320 and it was time for the first scheduled maintenance interval, during which the dealer basically does an oil change with a lot of inspections, and refills the AdBlue (urea) tank which for the Bluetec emission system.   This made it convenient to stop at Feldmann’s in the morning, unhitch the trailer in the overflow parking lot, and get serviced while working comfortably in the Airstream.

For those interested, the AdBlue tank required 4.5 gallons of fluid, which is about half the capacity of the tank.   This is despite about 7,000 miles of towing and 3,000 miles of general purpose travel.   So we have proven that even with a high percentage of towing, I don’t need to be carrying spare bottles of urea around between service intervals.   We’ll have another service at 20,000 miles and the AdBlue tank will be flushed and refilled at that time.

In the afternoon we had a couple of hours to zip over to the famous Mall of America (just a few miles down the road), just to say we’d done it.   If you like malls, this is heaven, and if you hate malls, well … it’s hell on earth.   Like most things, it is what you make of it.   One nice perk is that you can buy a Caribou Coffee and then walk around the mall getting free refills at any of the other Caribou Coffee outlets, which are everywhere.   That, of course, was all Eleanor needed to know for her bliss.

We didn’t have time for shopping and we didn’t really need anything, even from the “Barbie Store”, but we walked all three circular levels of the mall just for the exercise.   Then we ruined any possible benefit of that exercise by pigging out at Dave’s Famous Barbecue.   Overall, I think that’s a net win.

The MBCA meeting was held in the parking lot beside the Airstream. Imagine about a dozen people milling around in a parking lot with a few distance sodium lamps providing dim light, all excitedly talking about Airstreams, travel, and Mercedes cars. Beside us the representative from Feldmann’s set up a table with desserts and drinks, and of course each of the members showed up in their Mercedes.   This group is a lot like the Airstream’s WBCCI group in age and obsessiveness, and like Airstreamers they own everything from vintage to new (and often several of both). Airstreamers aren’t all millionaires, despite what people think, and the same is true of Mercedes owners.   The ones we have met have turned out to be very nice and very dedicated to their cars, even the old clunkers.

Speaking of clunkers, the other noticeable element in the parking lot was several rows of older SUVs, pickup trucks, and minivans.   These are the remnants of the “cash for clunkers” program, and all are destined to be scrapped under the Federal guidelines of the program.   They were a pretty rough-looking bunch, especially when contrasted with the new Mercedes and Nissan cars being unloaded nearby.

We’re on the way out of town now, heading for a quieter spot for a few days, so we can catch up on work, laundry, groceries, and homeschooling. It looks like the SPAM Museum will not be on our route after all, due to limited camping opportunities in the area. We’re moving west again ….

A tip about tires

I’ve written about tires so many times in the past four years that I am wary of bringing up the subject again.   I have to wonder how many blog readers’ eyes have glazed over permanently.   But I keep learning new things, and I feel obligated to share them here in the hopes that these lessons will help someone else.

A few weeks ago I had mentioned on the blog that we had unusual tire wear along the outer edge of some of the Airstream’s tires, and this was the thing that caused us to go to Jackson Center for an axle alignment.   As it turned out, the axles were out of alignment. After the service, I resolved to keep an extra sharp eye on the tires, to see if the wear returned to a more even pattern.

This morning, after yesterday’s 350+ mile tow, I noticed the left rear tire was looking very funky.   Wear was occurring rapidly in isolated spots, and there was a distinct bulging in the tread.   Those are the signs of a belt breakage inside the tire, and I’ve seen them before.   We got some local advice and towed the Airstream a few miles over to Mill’s Fleet Farm in Wausau for a replacement.

These days, when I have a tire problem, it is my habit to remove and reinstall the tire myself.   This saves a lot of hassling and potential screw-ups by technicians who (a) don’t know the proper way to jack up an Airstream; (b) will use an air wrench to over-tighten the lug nuts; (c) want to argue with me about using tire pressure sensors (“Just throw those things away, they’re the cause of every stem failure I’ve ever seen.”)

So in the parking lot we removed the left rear tire (a Carlisle) and sure enough, it was a disaster.   The tire rolled like a jelly bean, and had bare patches on it.   It looked fine the day before, which shows how fast they can deteriorate once a belt starts to separate, break, or shift.   We rolled it over the shop, where it was quickly replaced with a fresh tire.

Then I took a careful look at the other tires and discovered that the left front tire (a PowerKing TowMax) also looked a little suspicious.   I asked Jason, the Service Manager, to take a look and he agreed it was probably also suffering belt breakage.   We removed it out of caution and confirmed that it was indeed out of round.   While it wasn’t as bad as the rear tire, it was heading that way and needed replacement.

So now the question was, why were these tires failing?   At first I was theorizing that the tires were stressed.   They had been wearing in a particular way before the axle alignment, and now they were being forced to wear differently.   Could the change in alignment be the cause?

Then Jason pointed out something interesting to me.   Both tires had been patched (we have rolled over a lot of road debris like nails and screws in the past year).   Both tires had belt separation centered in the exact spot where the patches were installed.   At last, we had a smoking gun.

The problem was that these were “flat patches”, meaning that they covered up holes from the inside of the tire like patches on your blue jeans.   Flat patches do a good job of holding air, but the original hole in the tread can still allow water to get inside the tread.   Over time, that water will rust the internal steel belts of the tire, and suddenly they break.   This is what I believe happened to my two tires.   Left unattended, the next step is a blowout.

The Rubber Manufacturers Association says not to use flat patches.   The recommended and best way to patch a tire is with a patch plug, which is a patch that also fills the hole permanently and keeps it dry. Too bad that the last few shops to work on my tires never mentioned this option.

Well.   I am glad that tire inspection vigilance prevented us from having a more serious problem, but on the other hand I wish I’d known about patch plugs before.   A pair of them might have saved us from buying $200 worth of new tires today.   I may begin carrying a patch plug in my spare parts kit, just so I can hand it to a tire shop guy if he doesn’t have one.

The two tires on the right side of the trailer are fine so far.   I don’t recall if either of them has been patched in the past, but they are wearing appropriately at the moment so I’ll just keep an eye on them.   Both of them, by the way, are Goodyear Marathons, and the rear one is actually nearly worn out, which suggests that it is approaching 30,000 miles.   My experience with numerous trailer tires over the years has been that no particular brand holds up any better than the rest, so I buy whatever is available.   At this point we have three different brands rolling on the trailer.

Interestingly, I had been noticing since Grand Rapids that our fuel economy was mysteriously declining.   We normally get 14-15 MPG towing with the diesel, and suddenly we were getting 12.5 – 13.3 MPG.   It seems that the tires were the problem.   Now that we’ve replaced the bad tires, we are back to normal fuel economy.   The broken belts “squirm” as the tire rolls, and in addition to causing rapid tread wear, this apparently increases the rolling resistance as well.

We are in Minneapolis tonight, parked on the street in a quiet neighborhood (with permission of the homeowners and their neighbor).   Local law says we can stay one night if we don’t unhitch, and that is our intent.   We had dinner on the deck with our hosts this evening on this balmy 82-degree September evening, and will be heading to Bloomington for routine car maintenance tomorrow.   Now that we are here, we are done with big-mileage days for a while.
