Interesting. See, I view State differently. They're as irrational a fanbase as any, but their alums are not very obnoxious, IMHO...probably because they don't win that much that often. On the other hand, in my experience, UNC/Duke fans and alums can be pretty damn obnoxious (on the whole I mean...have a handful of friends and many clients who went to UNC and Duke and they are awesome). Most of the State people I know are generally pretty humble, hard-working, intelligent people who I could drink a beer with. Most of the UNC/Duke crowd I know think they're more important and smarter than they actually are. That's the stuff that drives me crazy. For example, I grew up in a really small town in NC and a lot of my high school went to UNC and they'd never get in now (this is 20 years ago). Even my sister got a full ride to UNC and she's an idiot, but I swear to god her and all of her UNC friends think they are astronauts.
Anyway, I'm good with State being our rival. That's better than BC, although I'd rather have it be GT or UVA if we're talking strictly ACC and not the proximity to Wake.
