I met a buddy in Moab, UT for mountain biking.  After an evening out in town, we headed back to our campsite and discovered a 4 wheel drive trail.  Unknowingly this trail took us up Lion’s Back.  We drove up the slick rock to about the 2:25 second mark in the above video.  Keep in mind we did this in the dark and then reversed all the way back down, in an AWD Toyota Highlander.
