Moab, UT. The campground is Lion's Back -- I think it's named after the rock formation our intrepid morons are driving in the pictures.

And yes, the tire marks are kind of annoying. The Navajo sandstone in the area gives a nearly miraculous traction to tires, but with any traffic it becomes black. This sandstone, incidentally, is one of the reasons that Moab is heaven for mountain bikers.
