We haven't seen them all yet but so far vote for Utah and Arizona. I think as soon as we get to Montana and Wyoming they will probably go on our list. By myself, aside from RVing, I vote for some of PA and some of Arkansas and Missouri. California, while not our favorite state, has some beautiful country in the far north and the Sierras, Lake Tahoe, as well as the Eastern Sierras, June Lake and that area.
Happy trails......................
