1957 Catalina Grand Prix for Motorcycles

I’ve seen a few clips here and there from Catalina, but never anything this comprehensive. This collection of 22 minutes from the 1957 running of the 100-mile Catalina Grand Prix motorcycle race is absolutely fantastic. The chaos of that start is crazy. That everyone seems to just get up and start their bikes back up and continues is even crazier.
