This outlaw bike club is now one of the major OMGs in the US, which puts them amongst the Angels, Pagans, Outlaws, Bandidos, Mongols, Warlocks, Gypsy Jokers & Galloping Goose. They were formed in 1966 in Niwot, Colorado, and formed a second chapter in 1968 in Iowa, then adding more chapters in Arkansas, Florida, Illinois, Indiana, Kansas, Kentucky, Louisiana, Minnesota, Mississippi, North & South Dakota,Tennessee & Wyoming.
The club later on took the route that other big clubs have taken by establishing clubs in other countries, and set up their first European chapter in Munich in 1998, then setting up three more German chapters in Freising, Gangfoken & Nurnburg, then in 2007 another chapter in Viernheim. They suffered a number of arrests and jailings of members over the last ten years for firearms and drug offences, but they did cement friendships in Scotland by a contingent visiting the Blue Angels in Glasgow.
There was a documentary about the annual Sturgis Rally shown on TV years back, and there was footage of the SOS. One was trying to properly interpret the Latin logo that is on their colours and one other kept correcting him, annoying him so much that he threatened to have the knowall knocked back to being a prospect. Expect more European chapters from this club.
