Swing On Site Family. Hardcore Crew based in the Ohio/Pennsylvania region and Japan. Specifically North East Ohio, Western Pennsylvania, and Tokyo, Japan. Begining in the mid/late 90's in Youngstown, OH with minor crews of teenagers who grew up to become Hooligan Crew. It was later decided (in the early 2000's) that a crew would be formed of friends from neighboring hardcore scenes in Pittsburgh, Erie, and Cleveland to strengthen the hardcore scene in the region as a whole.
SOSF is a hardcore crew.
