Our stadium (55,000) is bigger or roughly the same size as:
Colorado (53,750)
Kansas (50,071)
Kansas State (52,200)
Baylor (50,000)
Texas Tech (53,000)
OSU (60,000)
Guess no one will go to those schools because of their "high school stadiums."
We could always do like Nebraska and mark the seat widths for something that is appropriate for a class of kindergardeners. We could easily "squeeze" in another 15-20,000 bodies. Seriously, the Nebraska stadium has some of the worst seats and access aisles of any stadium in the country.
