Only fans I have been subject to in a "mob" setting are patriots fans, and they are amazingly friendly.
Talked with a lot of people at last year's parade in Boston. Was also my first time in Boston on foot.
So when the women got lost and I got tired of looking for them, I decided to go sight seeing. I saw Paul Revere's grave as well as a bunch of other historic figures all in the same graveyard. It's really odd because it's inbetween two rather large skyscrapers in downtown
But yeah, I don't think I had any bad experiences with any of the fans. (with the exception of the "gangsta" crowd but I think they were there just for the sake of skipping school like c00l d00dz. I bumped into a few and they were right out pricks. THERE ARE 1.5 MILLION PEOPLE IN A SINGLE SQUARE AND THE SURROUNDING BLOCK!! YOU WILL BUMP INTO PEOPLE HERE AND THERE)
