The Yankee fans down here in Tennessee aren't threatning or anything, but they're still annoying. But there are an awful lot of Boston and Yankee fans down here. I was sitting in my college library and looked around. Including myself in a small library, I counted 4 Yankee hats, 3 Red Sox, and Cardinals hat. This was out of about 10 people in the library. Baseball is pretty big around here.
The only time I ever had a problem with a Yankee fan was one who had a poster of Derek Jeter on his locker. It said "WINNER" at the bottom in big letters. Someone crossed it out and wrote loser in its place. And since I was the most vocal Red Sox fan.... I was the lead suspect. He got pissed off and shit, but we found who did it. I've never had any yankee fans rip off my Boston hat or anything like that.
Have you seen a Devil Rays game when the Yankees are in town? 3/4 of the crowd is pro-Yankees!
