Bottom-line, excessive alcohol consumption is slowly but surely ruining the game experience. The last time I went to a game at the stadium, my wife and I, and a 12 year old boy who was with our group, had to listen to a vulgar ("F" word for every thought and comment which he felt free to share with everyone in the section for every play) loud mouth drunk the entire game. And in front of us was a girl who came into the stadium and pass out as soon as she sat down, only to wake up and start groping the guy she came with. This has been the norm of my experiences in Buffalo, not the exception.
Yeah, it was a lot of fun.
And I do think it is effecting attendance, next time you're watching a game on TV, pay attention to the number of empty seats as the typical stadium. Honestly, I hope the attendance thing becomes a serious enough problem that the league will get serious about doing something about it. Because the only that will affect change is money—a few good law suites would help.
Unfortunately, until the Bills and the NFL get serious about controlling this kind of behavior, there will be plenty more stories like that night last season.
By the way, I've been to two games in Miami, and it was a much more enjoyable experience, even as a fan of the opposing team.
