Hello RTA. I am a rookie here (I can't even figure out how to post a new thread). I am coming from the East Coast next summer (July or August) and would like to land in Denver and do the loop with Yellowstone being the mid point. Maybe hit Laramie, some hot springs and Cody. How long should I plan for this trip? (Maybe a ghost town too). Also, do you suggest an RV (a class) or a van?
