I'd like to hit the most interesting dirt riding between Lake Tahoe and Moab, UT. We're planning to do the trip over a few days or a week during May. Dirt roads, 4X4, and even singletrack if it's not super technical. We'll be riding big singles and we're good dirt riders, but the luggage slows us down too much for the really rocky, narrow stuff. Got any gpx I can use? Thanks much!!
