Hi Steve,
The Pro Circuit parallel to NASCAR doesn't hold water. We do not have established followings to three or more manufacturers with a large fan base supporting each. In beachcat sailing we do not have the equivalent of the Ford, Cheve, Dodge race car base or fan base. There is one parallel we can have to NASCAR and that is 'THE CHAMPION OF CHAMPIONS'. The Champion of Champions Race is held in identical cars. It is one design car racing! As I understand your effort, this is your goal.
Bill
