I have actually driven my jeep on a few quad ATV trails. I called them goat trails, because they are very narrow. And yes it is very difficult to drive on them, you have to be extra careful, because if you get stuck and need help then you are pooched. The thing is on those trails, you have to drive over large tree stumps, and sometimes there are grown trees very close together that you have to navigate through or around. I didnt know the proper etiquette at the time when I did this, as I was new to 4x4ing. But I won't do it again.
