Yes, on most of the trails in Western Colorado between Ouray and Silverton. I don't do Black Bear or Poughkeepsie, but all the others are fair game. If you get stuck out in the middle of nowhere, it will coast a fortune for someone to come pull you out, i.e. the road side assistance that most insurance companies provide does not cover "off road" rescues, but other off road people are really good about helping others out of a jam. You do have to be careful -- seems every year someone rolls their rig off the narrow Ophir pass road.
