Why are 2 Wheel Drive vehicles not allowed?

Our Gang 4 Wheelers originated from a group of people who were 4 wheel drive enthusiasts and the first races happened at ponds that were only accessible by 4 Wheel Drive trail.  The sport, as it is today, has evolved from that beginning.  This includes the rule that vehicles must be Four Wheel Drive or All Wheel Drive to participate in any of our events (races, practice, etc…).  At this time, we are limited on time (only 6 weekends per season) and current volunteer and sponsorship levels do not support the successful addition of the extra classes and drivers that opening the vehicle classifications would bring.  As an alternative, you can check into other clubs in Colorado that put on races or ice driving classes for non four wheel drive vehicles.
