Milius say that his surfer gang during teenage years was hugely influenced by the Beat Generation -(now I pretty much understand where all his "punk-like" attitudes come from).
The Beat Generation in America during the 50's planted the seeds of anarchism which later would rise in the form of two movements: hippism and punk. The surfer gang of Milius disliked hippism (Milius never used drugs because he was mentally fragile, also disliked naivety and anti-violence of hippism) but was close related to punk in terms of style and agressivity against civilization (breaking the rules, to find freedom).
