The plan was to drive a mile down unpaved Comb Wash Road to the site of some Anasazi ruins. But the road crossed a dry creek bed, which looked deep enough that the RV would get stuck in it. Since we didn’t think it wise to go forward, and couldn’t turn around, we had to back up the road (a slight grade) until there was a modest clearing on both sides of the road that allowed us to do a many-point turn. But once turned around and proceeding back toward the camping area, we got stuck in the sand. So we backed up a bit, then got rolling forward again using some ‘tractor treadmarks’ on one side of the road for traction. We had looked forward to seeing the ruins, but the road was too sandy for our bikes, and it was too far to walk to, at least in that heat.
