I just put up a few pages about my trip to Utah last summer (2002). In short, it was spectacular! Utah is very ATV friendly, and the Paiute ATV trail is awesome! http://public.csusm.edu/RTrussell/utah/
This will definitely be something I'll do again, because in two weeks I don't think I saw but a smidgen of all there is to see and do there. Ghost towns to gullys- you can ride it!
