Yellowstone
We drug the camper to Yellowstone, stopping on the way at a small campground west of Lander on the way. We camped outside the park on the Montanna side, driving into the park to explore during the day. It's definitely worth the trip, though we found it a little crowded this time of year.

The landscape and wildlife are beautiful, and the unusual geology interesting. The highlight was a bison that crossed the road in front of us, then turned and walked past us in the opposing lane, passing the truck window close enough for me to touch.
