ND92, whatever you forget can usually be bought there or borrowed. Everyone is, usually, very generous with their time and materials so there's really no worry. I think my first year in Moab I had a hand held CB (which you can borrow if you don't have a CB), a box of common tools and some water and I did just fine. If you're going to go super agro, though, you may want to bring some more tools and some spare parts. You'll have a blast no matter what.
