Doesn't surprise me tbh, Boston people are ruthless. I've told this story on here before but, when I was at Seattle watching a Yankees game, Mariano Riveras last year. I went to the Yankees bullpen to watch him warm up, the place was surrounded by Yankee fans. Anyways because I was drunk and like to start stuff I started yelling "Go Mariners Go", man the looks I got finally someone said your cheering in the wrong area, so I said "No you're cheering in the wrong stadium", kind of stumped him, but looking around everyone was pissed so I walked away lol.
