Miami (FL) is currently in a 3 game series with them, playing in Boone last year.
Chapel Hill is a nice town, I'm just not a fan; took classes there and wasn't overly impressed. Their fan base (and I know they're having a down year) is very much fair-weather fans. Talk to any UNC fan, it's basketball first, then women's basketball, and maybe football after that. They've spent some $$$ making Keenan nicer since you've visited, but still, the stadium wouldn't be packed.
App State, in my eyes, is nothing like a community college. It's only 30% smaller (in acreage) than Auburn and has almost 20,000 students. It seems very compact because of the mountains, but their fan base is pretty loyal for football; and with some of the weather they play their games in, you'd have to be.
