Stayed at the Cheyenne KOA, east of the train depot along the interstate, Cheyenne seemed nice. Stayed about 5 days.
My boys loved the UP running just about all day long. Good bars, restaurants, a little too hipster it seemed, I could live with that. Laramie looked like a lumber town with a college campus tossed into the mix. Rawlins.....truck stop. Rock Springs, was only a fuel stop and two new camper tires, but it seemed like small town USA. Not too bad.
So, my experience with Wyoming is limited to the I-80 corridor, and fuel stops.....Wyoming seems great.
