Nebraska's attendance for VB is very impressive. It basically reaffirms my sense that in the Midwest, people attend university events, especially at the State U. whether sporting or otherwise, on a regular basis and that doing so is a part of growing up with public institutions and Land Grant colleges. The entire mindset out there toward public universities is much different than in the Northeast.
My first real encounter with this came when I was doing a Master's at Ohio State many years back. Beyond Buckeye football and its fan following, I was impressed by how more than 3000 people would show up on a regular basis to see travel films, presented by the filmmakers, at Mershon Auditorium on a Friday night. I realized then that people out there are really tuned in to what is happening on the campuses in their area.
It also helps to have network TV stations in all of these states that promote such activities merely by talking about them. I sure wish NJ had that.
