Blackstone Rangers at 35th and Wentworth. Very dangerous group. Also C.O.M.C...Chicago Outlaws Motorcycle Club...which then became one of the earlier chapters of the ANGELS and the first one in the midwest. Many ethnic gangs back then out of Buck Town, South and West Side, Uptown, Austin, Cicero, Stickney and as far south as East Chicago and Cal City. Very tough guys. Boxing refelected this ethniticity. Irish, Italian, Polish, Black, Greeks, Latino (mostly Chicanos from Desplains). The ones you referred to came after I moved (thank God)...............or I would have ended up in Joliet or Pontiac if you get my drift. Fortunately, I got a scholarship and escaped that hell hole. I never looked back.I am one of the few Chicago natives that did no particularly care for growing up in that environment of mean streets and brutal rascism....but I believe it has since been yuppified.
