Pro tip: The only game they sell tickets to, is the K-State game. When I was in college, we figured out a system in lawrence. Someone would go in early and then leave and they'd stamp their hand. That person would come to the tailgate and roll his stamp on our hands. Guess what? It will show up on your hand as well and you can just walk right in. Super easy.
Obviously i'm not a poor anymore, but this might be a good tip for the youngsters.
