Yes, i grew up in SF and remember racing on the great highway in my 70 six-pack challenger. Lots of my friends had muscle cars and we would meet there on Fri and Sat nights. It was so much fun. We would just hang out, race and check out the cars. The SFPD didn't intervene that much. In fact, I recall Evening Magazine (KPIX) did a story on the action. Those were great days.
