Do most of them drink? Safe to say yes. Are all of them getting drunk or even buzzed to the point that it significantly changes the experience? I for one do not think so. I have not been to a lot of venues but I have been around a little bit and I don't think the drinking is what made the party. It always seemed like the heaving drinking was with the students. BYU students are not the problem, they have been showing up 1-2 days early all season to get seats and be loud.
