I don't think it will have much affect on fan behavior. Folks who are going to drink so much they become rude obnoxious will come in stadium drunk or sneak in bourbon or vodka.

Beer sold will be so expensive, only few willing to drop alot of $$$ will be able to buy enough to get sloppy drunk.

Might as well go ahead with it, we need the revenue. Maybe only license to local or virginia breweries. Might consider Wine as well Chateau Morrsette
