You are sooo right! My family (2 daughters, son-in-law, spouse and I) attended the Pistons game at Conseco about this time last year.
We endured 2 hours of the most filthy, perverted screaming from about 10 drunk Pistons fans seated right behind us. They used language I have never heard uttered outloud in public.
There were many small scuffles around the arena during the game and security handled those first. Finally, about 15 minutes from the end of the game, security came and told the screaming drunks to shut up.
Ruined the entire evening for us.
The fans at Conseco are civilized. It is that simple.
