I have only talked to one UND fan EVER that I didn't like. After my team beat the Sioux in 99 your fans were complimentary, nice, cordial, etc. After that game I really started to like UND and its fans. While I believe those things happened, I certainly don't think it's indicative of most UND fans.
Having said that, I've been to Florence twice. Southern hospitality is EXTREMELY overrated. Florence felt no different than anywhere I've been in the Midwest outside of Chicago. I think in general, people in "flyover" country are good, polite, cordial people.
