SGM
Skaters Gone Mad, originally a group of skateboarders from various parts of Sacramento, founded in 1995. Became famous for pranks, graffiti, fights, off-the-wall crime, and vandalism. Later evolved into a crack team of vigilante crimefighters who cleaned out the infamous C-Street Trainyard drug-dealers. Unofficially disbanded in 1999.
SGM is short for Skaters Gone Mad.
