I too was one of the K-State fans in attendance and I have to say that I really don't care if I ever make it back for another game.
All I heard about leading up to Saturday was what a great gameday experience it was in Lincoln and how Nebraska fans were the classiest in the nation. Those statements couldn't be further from the truth. As long as I was tailgating with friends and relatives (all Nebraska fans) everything was cool. There was even a roaming band that played the K-State fight song. Great! Whenever I ventured away from the tailgate (to use the restroom, go into the stadium, etc.), it was a completely different story. Nebraska fans referring to every K-State fan they saw as a "Purple faggot". I was turned away from a portable toilet by three inbred, overall wearing jackasses until I took off my K-State jersey (which I refused to do...just found another bank of crappers). The non-stop bitching by the fans about the few officials' calls that didn't go Nebraska's way was almost unbearable. The walk out of the stadium and back to the tailgate after the game was even more fun constantly being reminded that K-State will never win a national championship and that Nebraska has five, Pelini is a mastermind and the best K-State could do was pull a poor old man out of retirement, etc. Well, whoopity f*ing doo. Even as a student I never treated opposing fans the way I and several other K-State fans around me were treated.
I've been to Oakland for a Raiders - Chiefs game and found the fans in the "black hole" to be more respectful as a whole (not kidding).
Oh and as far overall "chill factor" for pregame, stadium experience, I can think of a few other venues that blow Nebraska away!
You stay classy Nebraska!
