in response to the point about wearing a sox cap to yankee stadium i agree. I have seen many an opposition fan get beat up or treated really poorly at yankee stadium, not something yankee fans should be proud of.
In contrast i sat in the bleachers of fenway last year with my girlfriend, both of us wearing yankees gear and everyone was really cool and respectfull. i anticipated the worst but was pleasantly suprised
of course a lot of people busted my balls but it was all in fun and not mean spirited at all.
so while red sox fans are definitely way more annoying around town, in my experience they are great hosts.
