I live in SLC. Riding in Southern UT is great but don't limit yourself to Moab.
There are many other options that include camping in solitude away from the little town that Moab is.
Look at this map of state parks:Utah State Parks | Utah State Parks
West of Green River (which you'll travel through to get to Moab) on I-70, there are tons of unmarked trails that lead to opportunities no one tells you about.
I've seen countless Indian artifacts that someone w/o the spirit to go off road will never see. So go all over Southern Utah, not just to Moab!
