Make sure you visit Moab. Ride in the mornings, and bring lots of gas. After that, take a quick trip to Little Sahara Recreation area, but don't turn south to the dunes. Go west, unload, and then ride to the north. GREAT trails. If you like dunes, you can ride them free by riding to the south of the road.
While I live in Idaho, I have race the Nationals in Utah for years. Great place to play.
