Mark my words, 25K plus, no doubt. You guys aren't students, you aren't on campus every day seeing what I see. In my time here, I've never, ever, ever, ever, seen them hype a game like this. Ads ALL OVER campus, daily email reminders, multiple ticket locations....they're going to go WELL over the 8K student tickets, and it'll bleed into the GA section without a doubt. There have been commercials, ads in businesses (remember the local business competition to see who can sell the most 2 for 10 tickets...), et cetera times infinity.
Honestly, 25K would be a disappointment in my mind from the amount of hype for this game. The only reason we won't get there would be because of some apathetic alumni. Get the hell to the game, the students will be there, and so will the community. Pay a babysitter, do what you need to do. This is a once in a decade type of opportunity for UNT...a NATIONALLY TELEVISED FREAKING HOME GAME. Anything other than the funeral of a close family member, or a job commitment you can't get out of, and I call weaksauce on your excuse.
