hmmm.....possible classes......an interesting question.....
Center Steer (Altereds, Dragsters, Floppers)
Door Cars (Full Chassis, Big Tires, Nitrous, etc)
Bracket Style cars..(i.e. Gator Gumbo / Thunderhorse)
Daily Drivers (Rental cars included

Awww, Hell's Bells.....4 car fields would be fun!!!!!............
(in the even of major performance differences in the Center Steer and Door Car classes......"Lengths" could be "negotiated".......
Perhaps have the winners of Center Steer and Door Car match up for a single run (with lengths as necessary) for Bragging rights????
