          Example:  If a Hobby Stock car is going to compete in the Street Stocks on the same night,  one driver will pay a car and                    driver entry fee for Hobby Stocks, and a different driver will pay a car and driver entry fee for Street Stocks.  The swapping              of the 2 drivers is not permitted at any time.  The registered driver will compete only with the car he/she registered with. A              substitute driver is ok if that driver pays another drivers fee, and is not the driver of the car in the other class.  Plain and                    simple: NO ONE IS ALLOWED TO DRIVE BOTH CLASSES WITH THE SAME CAR, AT ANY TIME.
