University of Iowa Official Athletic Site Gameday
Actually it's pretty recent, August 2011 recent.
Oh yea, Mo $ = Right?
Your linked article in your first post was from 2010, and was why the PSU game was mentioned as we played PSU at night in 2010. Nice try.
My point being aside from being able to walk anywhere you want with a beer the rules haven't really changed at all. For people to complain as much as they do about the changes you would think the police were walking around limiting people to 4 or 5 drinks. Anybody can get is drunk as they want tailgating at an Iowa game as long as they don't act like a moron. It really is that simple.
