My two friends and I are driving from Baltimore to Seattle at the end of June. Not too much time, so we are going to knock Baltimore to Chicago out in one red-eye drive and enjoy the West. We are camping the whole time (tent!) and are looking for good camp sites along the way. Obviously, if the weather's terrible or if there's nowhere to set up, we would stay in a motel or sleep in the car...but we really want to tent the whole way!
So we're going Chicago to SD, through Badlands and through Custer Natl. Park, over to Yellowstone and up to Glacier National Park before hitting Seattle.
We don't need a ton of amenities - would definitely prefer location and beauty over RV's and playgrounds. Showers would be cool every now and then... Any suggestions or recommendations for old-fashioned camping along that route?
