Here is a nice video of the muscle beach gang from the 1970's performing some flying rings feats. (quadripple back flip, can you spell 'air awareness'?)
The atmosphere around this beach, then and today (even though more then) is electrifying for someone interested in strength/acrobatics/handstand and balance/bodyweight conditioning/sports/sun/tanned bodies. I got a chance to train there a couple of times, and it is a great experience.
Ido.
