18 wheelers and small forest service roads going up mountain not a good mix. following GPS gone bad. Two weeks ago. Fourche mountain. Arkansas. we had to climb the hill with our rzr's in front of the cab and go through the trees to get around the truck. driver said we were first people he had seen after getting stuck (3 hrs.) Behind where I was standing taking photo was a tight turn. no way he would have made it. you can see his tire tracks where slid back down. large drop off on left side where the trees are.
