The U of MN wants to have it both ways. They want fans to show up. They say they want a "vibrant game-day atmosphere."
But they won't do the things they need to do to make that happen, because they're so afraid that somebody in the neighborhood might complain.
If you want a game-day atmosphere like IA or WI, then come out and tell the neighborhood, and tell the city of Minneapolis that Gopher Game Day is an event, and there are going to be crowds, noise, music, people having fun (and yes, tailgating and (gasp) drinking adult beverages.)
If you want a party, then make it a party - not a junior-high sock hop.
and yes - tell the city of Minneapolis - the U of MN Marching Band is marching down University Avenue, and if you don't like it, tough.
It's called UNIVERSITY Avenue for a reason.
