Wow all the posts so far are good, been to them all we particularly like the black hills, Custer SP, Beartooth pass is magnificent been there twice, Utah is spectacular also got to go back may be next year. Canadian rockies been there probably 10 or more times, Yellowstone 4 or 5 times, I guess I just love everywhere, we are driving camper site seeing tourists, also love the no interstates as we drive strict 55 for fuel mileage. We usually just get the map out, look for those dotted roads on the map and go drive them. My personal favorites are west, also been east all over but west has my heart.
