I grew up in the Boston area. Married a NY guy who is a big Yankees fan. We returned to Boston University to get our Masters degrees. We also go every so often to visit family, and/or just a vacation, since Boston is such a great place. We NEVER bring or wear any Yankees gear, even though at home we own and sport a ton of it. We not only root FOR the Yankees - we watch stats, and root AGAINST the Sox. (the priest in my old MA church would say, at the end of Mass - "Hail Mary, full of grace . . . . keep the Red Sox in first place" - or if they were having a bad year " . . keep the Yankees out of first place!" All the Yankees/Sox stuff STAYS HOME in NY. But it could be worse. Our son lives near Philadelphia, and is a Giants fan - and going to a football game in Philly is seriously dangerous for MOST other fans! So he doe snot wear any gear. His wife is a huge Flyers fan (wearing all her stuff!), and they go - and there is no problem with anyone being rude there, ever. Even if he wears a Rangers jackets - his WIFE is screaming so loud, that people figure that covers them BOTH for rooting.
