WIth regard to the OP, to say this will be in front of "61,500 hostile Cyclone fans" is wishful thinking. As we all really know, there will be at least 10,000 fans for that school to the east. Shoot, they even get about 200 or 300 of their fans into the Sukup End Zone seats.
So many Cyclones sell their tickets to Hawk fans, in addition to the Hawks who buy online or even buy our cheap ticket packages just to get in the gate for this one game. The Cyclone fans who do attend are going to have to kick up their involvement a couple notches to truly make it a hostile environment. My guess is that this will essentially be a non-factor in the game due to there being so many Hawk fans that get in our stadium. And I assume this is basically unavoidable and that Cyclone fans do the same thing when the game is over there. But I have never been to Kinnick so I have no first-hand knowledge. Perhaps others can clarify if this does indeed work both ways.
