In my experience students don't really show up for wrestling meets unless they grew up in a house where Iowa wrestling was closely followed. We get in for free, but I don't think where the most of the students sit is actually a dedicated student section. I think it is set aside for general admission, but students who get in also sit there.
Could be totally wrong though, but when I sat in the student section earlier this season (like at the Nebraska meet) there have been just as many families/middle-aged folks as there have been students down in there, if not more
I do know quite a few people who went to this one though, but that was because they worked the event in some capacity and got free tickets for it.
