Ah... I missed a good thread while on vacation. For all alcohol consumption, here are my 2 cents: the "drinking section" of the stadium, although impossible, would be perfect.
The 2 sides of this argument are that there are people that don't want "drunken idiots" ruining the gameday experience for them and their children, and there are people who like to get crazy and have a drunken good time.
I think both certainly have their place, and I will most likely support both during some time in my life (although currently I always drink some gameday Jack). My solution would be that young alumni/students/other crazy folks occupy certain areas of the stadium, while families/elderly/straight-laced folks occupy the others. Again, obviously this would never happen, but it would make things much easier.
