Outlaw biker gang subculture... :D PLEESEE!!!!!!!?

Bikers. Are they the dark and dangerous side of tribal culture, or are they rebels in search of a cause? Whatever the case The Nomads, Gypsy Jokers and others do represent the 'outlaw' side Of Australian tribes. Why do they stick together? What’s biker culture all about? Should we be Afraid? Are they simply a brotherhood of bikers, from whom the public has nothing to fear? Apart from the occasional bad apple? Or are they billion dollar crime organizations, involved in Drugs. Gun-running and murder? Or does the truth lie somewhere in between?
