Even as a drinker, I'm against this. Main reason is because I don't want underage kids getting it. They always try to find a way to get the alcohol. People bring in their own stuff and get drunk, but now if they do this, you'll have to deal with more drunks.
I don't think I could go to BDS, sit near people that have been drinking and get liquid courage, and hear them talk shit the entire game. Imagine this scenario: You're sitting in BDS with 'Bama fans on your left and a small section of LSU/Barner/Tennessee fans on your right and say about 1/3 of those fans have been drinking and its an intense game. You're asking for a riot to break out. I've been to Baton Rouge before and I've had all sorts of stuff thrown at me. Beer has been one and I tell you, those people get mad as hell when they lose and they will do whatever they can to exert their anger.
