When we picked up the sportsman class, we just allowed cars from other local tracks to come and race and we never really had a set of rules. After much consideration, we have decided on a set that allows the cars that have been supporting us to race as well as some other local cars to compete. We have combined the northern type sportsman cars with the southern Hobby class. With weight breaks in place, along with the other built in differences, it should be very competitive between teh 2 different types of cars, while hopefully increasing the car count.
