The USRRC and then the CAN/AM. One of the most popular sports car racing series of all time. Then we had F5000 which had some of the monster open wheel cars ever seen on road courses. The Formula Vee's and the Formula Fords proved a great training ground for up and coming drivers. And let's not forget the TRANS/AM series when America's auto makers jumped in with some real muscle cars and top names in the sport battling for the championship. A great era for racing at Road America and around the country.
