I don't know how many of you love old sports car racing, but I just ran across an excellent video of the USRRC race at Riverside in 1963. This is when the major drivers participated in many kinds of motor sport. I hope you enjoy.

 

Group 7 cars were some of the fastest road racing cars in the world at the time. As I recall, the Times GP was the penultimate round of both the USRRC and the subsequent Can-Am series.
