10 Notorious Motorcycle Gangs

Sons of Silence Motorcycle Club

Based out of Colorado, and controlling much of the Southwest and Rocky Mountain States, the Sons of Silence Motorcycle Club boasts 30 chapters across the United States and five splinter clubs in Germany. Altogether, the SOSMC is 275 members strong [source: National Gang Intelligence Center]. Founded in the town of Niwot, Colo. in the 1960s, the Sons of Silence have been engaged in a long turf war with rivals like the Outlaws since the beginning [source: Abbott]. The Sons are one of the few 1 percenter clubs to be allied with the Hells Angels, which means they have a lot of enemies for a relatively smaller club [source: Serwer]. They make up for the disadvantage in fire power. In 1999, a huge multi-state raid of Sons of Silence clubhouses in Kansas, Colorado and Arizona uncovered enough weapons to run a small army. Among the confiscated ordnance were dozens of machine guns, pipe bombs and even hand grenades [source: Abbott]. The club knows how to intimidate. Their motto, incorrectly translated into Latin in their colors, is "Until Death Separates Us" [source: Serwer].
