Yeah, what's up with that? Is Alaska pretty much a "Wilderness Area" and therefore no mechanized forms of travel?
Anyway, we visit Moab, UT at least once or twice a year (less than 2 hours away). The trails there range from real easy (gravel/dirt road stuff) to extreme (only custom built rock-crawlers). Since we usually drive these trails by ourselves, we limit the difficulty to medium (one step above easy) to mitigate the possibility of getting in over our heads and needing help. There have been times (like our last visit) when we have driven all day without seeing another vehicle.
The desert scenery & views are simply spectacular. There's no other way to describe them. Usually dusty, but hey, it's the desert. The trails themselves are fun to drive without being too challenging, but a good guide book is an absolute necessity.
