On March 1, 1964, the United States Road Racing Championship (USRRC) held two 150 mile events on the road course. Dave MacDonald won the first race in a King Cobra, Jim Hall was second in a Chaparral 2A and Bob Holbert was third in another King Cobra. Ken Miles and Dave MacDonald finished 1–2 in Cobra Roadsters in the afternoon race. Dave would lose his life a few weeks later at the Indy 500.
