Hi -- I'm picking up my son from Lander, Wy in August and we will spend a week driving to San Francisco. We've seen Yellowstone. This trip is about weird Americana -- if there is any along the way. Any thoughts on the best, most interesting route to take -- should we go to Jackson and Idaho Falls or down to Salt Lake City? I'm not familiar with this area at all so any thoughts on the best, not quickest, route are much appreciated!
