The Jeep people that go to Moab are mostly out of SLC. and are part of the Mall crawler Jeep fix up crew. Not saying thats bad, its what it is. You won't see those jeeps in other parts of Utah, they are very specialized climbers which is a sport by itself, just like drag racing.
west desert has lots of long range shooting, 50 cal and up, with a yearly event held in Wendover.
Border above Vernal into Wyoming has some of the best prairie dog hunting you will ever see. (coyotes, and sage grouse also)
and the Bookcliffs from the Colorado border to Price has great cougar hunting.
