A better question would be how many classes use the Midget Chassis as a racing platform. A midget is a Midget the way I see it be it a 600cc upright or a full blown TRO National Midget and everything else in between.
Racing has always been Regional and I suspect it always will be. Some people have tried to change the name by calling them "XX Sprint" or "Speed Car" or "Speedster's", but when push comes to shove they are all Midgets. Some of the guys just spend a little more money on their Motors. How many classes of "Stock Cars" are out there???
