I'm not sure I see how this could be fun. Basically the point is to drive around a parking lot, no more than 35 miles per hour, never reaching third gear for less than a minute at a time. I mean, these guys don't even need a helmet or a neck brace for safety equipment!
It's not my thing either, despite my love for Jeeps and 4 wheeling. For the record, most of these guys wear the helmet, neck brace, a HANS type device plus straps for their arms and legs. Then of course there's the 1248-point roll cage.
