Hells Angels were not the only the outlaw motorcycle club to emerge in this period, but they fast became one of the most notorious. The club was founded in the Fontana/ San Bernadino area of California and its 'Berdoo' chapter still exists today. The 1950s saw more and more cCharters crop up, initially having little connection with each other. They would soon become, however, an integrated network of motorcycle enthusiasts, among other things, who had standard criteria for admission to the club. It came to resemble a military operation with rank and file rather than a club.
