Agree that the marching band (or even just the small troupe that travels from bar to bar on Fridays, if they still do that) should be part of the live music -- having an exclusive set of it's own on the plaza stage and then continuing to travel around the stadium, pre-game.
Problem is, the Iowa band SUCKS! Not saying the members are bad musicians, just saying they are the most impotent college marching band I've EVER seen. It's embarrassing when they're getting out played by Cy-band, 2:1, in Kinnick, no less! It's shameful and one of the biggest disappointments of the game-day experience that seems to be one of the easiest fixes -- just play some f-ing music, once in a while, rather than deferring to the visiting band!
The other game-day fix ... sell some beer. Simple. Will result in ZERO issues. Problem is the IC & UofI p.c. gang are to busy hiding from the shadow of "what if" rather than going all in to make each and every home game an all-day festival atmosphere that's a destination event rather than a buzz-kill.
