Campy fun but the mosquitoes in Wall were murder. I've spent 6 months in Haiti so I know bugs but this was worse.
We also stopped at the Pioneer Auto Museum in South Dakota . Not much on the outside but inside were 8 buildings loaded with great stuff.
My wife had to fly home for work from Sioux City. I drove from there to RV museum in Ekart Indiana (631 miles) in one day. I arrived at 10pm to find other people camping overnight in the parking lot so I joined them.
Interesting differences in Butch Cassidy (my 57) and the 54. Lots of similarities as well. Butch has the little removable tank in the kitchen cupboard for water and it dribbles down into the sink with a push button spigot. Bunk is the same, front the same and Butch has a Princess stove with an oven.
Anybody driving across the country should download the Ultimate US Public Campground Project app. It's a lifesaver when you're wandering without reservations. We found a place every night with it. Like this one in the Black Hills.
