I work with a bloke who is one of Weslo's "finest" on weekends. He has said that while only a minority of Sturt supporters are trouble, the few that are are worse than anything they encounter from any other side in the league, Centrals, Port etc. included.
I also know a young Sturt supporter that used to sit with the cheer squad nearly every week, niether of his parents have allowed him anywhere near the cheersquad for the last 2 or 3 years due to the same minority.
