My son and I took the XJ back in '06. We had a great time, the first night we were there it rained like hell which made the trails at least one number harder than normal. Had to be strapped four different times over the course of two days (twice in mud, twice on rocks). On the plus side there were three different obstacles where other drivers got stuck that we went right through. It's nice when you get through a tough obstacle and the other drivers are standing around cheering you on. Of all the events we have done I probably learned more that weekend than any other. The trail guides were great and really knew their stuff. In fact the whole event staff were great.
Just a slightly modded XJ with a little lift, some armor, four mud tires and a few decals, so far.
