Looking online I saw that it said about 4,800 was on campus housing capacity. So I'll say 1/3 of that to start ~1600. If you could get 10% of off-campus kids that would be huge (~800). So 2,400 I think would be the goal with about 3k (10% of in town residents).
5,400 is the target for normal games with 3 to 4 sell-out promotional games.
To be honest, Wednesdays and Sundays are extremely hard for me to make because of church responsibilities. In Nacogdoches, it still has an effect on attendance. Two years ago when our games were on Tuesdays, we really did have bigger crowds and it wasn't just Underwood holdovers.
