stimpy,

My late father-in-law attended the Yankee-Met World Series a few years back with my wife. He was a Mets fan. The game was at Yankee Stadium. He was wearing a NY Mets shirt.
I have to tell you that there's always a small percentage of fans that will show you no mercy if you're wearing the oppossing team colors.

My father-in-law said it was ok for a while; but after the 3rd inning, the real a$$holes started rearing their ugly heads. And this was an 80 year old man they were going after.

So if you're intent on wearing pinstripes in Beantown, goodluck.

Tell us how it turns out.
