Well Black's Beach was very isolated..You could enter from La jolla Shores Beach, Torrey Pines State Beach or down the path from the hang gliding runway. It has always had nudist come down from the University, and there has always been a mix of nudists and non-nudists. I went there when I was 12 or 13 as a looky loo, and fell in love with nudity. been doing it ever since.
the people in California are a lot more laid back. You can pass by Pople's Park in Berkeley on a nice day and see many students sunbathing nude and even a nude theater performance, with the police watching. Nobodyy really cares, its a lot different in the south, many conservative people.
