i know a trail thats 110 miles, all dirt road. about a 5 hour drive. it ends in a ghost town on the west side of salt lake. i've never done it, but i've read it in an SUV off-roading trail book. in the ghost town that it ends in, a bunch of trails brance of, the only worry would be gas shortage and ground clearance, also its very remote. tons of fun, im down if anyone else is. let me know.
