Yeah, I know what you mean by Boston. When I visited, you had to go with a group of people, and look like you couldn’t possibly be that talk radio personality, but that was about ten years ago. Oh yeah, and I was also warned not to wear a shirt for a team other than the Celtics or the Red Sox.
I was warned on my visit about 11 years ago, but I did get to see the historical sites from the American Revolution so rock on!
Yeah, it's bad like that, too. Just like wearing anything but an Ohio State football shirt in Columbus. Complete strangers will serenade you with profanity.
