lol.
seriously though, it's not the students, it's the old people that buy season tickets and then don't use them.
Granted I've only been able to make one game this year(EFF YOU GUYS I'M POOR AND LIVE TWO HOURS AWAY), and it was Sunday so the students weren't in town, but when I was at K-state last year they packed the student section fine. I'm personally betting the reason there are more empty bleachers at the top because everyone is cramming closer together at the bottom to get closer to the action now that there's something worth watching.
The old people that buy season tickets and then don't show don't have an excuse. They have assigned seats that they don't use. I can understand games during the week, if you live 2 hours away, but why wasn't Sunday sold out? I got some decent tickets for $15 a piece and enjoyed it, even if the game was boring as &@#%.
