The Sports Car Club of America (SCCA) is a club and sanctioning body supporting road racing, rallying, and autocross in the United States. Formed in 1944, it runs many programs for both amateur and professional racers. The SCCA traces its roots to the Automobile Racing Club of America (not to be confused with the current stock car series of the same name). ARCA was founded in 1933 by brothers Miles and Sam Collier, and dissolved in 1941 at the outbreak of World War II. The SCCA was formed in 1944, at first as only an enthusiast group. The SCCA began sanctioning road racing in 1948, with the inaugural Watkins Glen Grand Prix. Cameron Argetsinger, an SCCA member and local enthusiast who would later become Director of Pro Racing and Executive Director of the SCCA, helped organize the event for the SCCA.
