We went to a SB party this year. One "all-in" Pats fan, who was invited, was a no-show, for fear that they would loose. One who did show, was on the verge of tears, till the come-back. And, yes, I doubt they were Pats fans before 2000.
I'm a BILLS fan because that's my home, ans I grew up with the team. They're not the; North of Pennsylvania BILLS, or the WNY BILLS, or the South of Ontario BILLS, they're the Buffalo BILLS. I say that because these people are from Maine! New England, maybe, but Boston, hell no!
