I live between DC, and Baltimore. I can not stand the Ravens, or their fans. I took my daughter to a game vs the Bills, she was 10 at the time. The Ravens fans threw items at us for wearing our Bills jersey. The Skins (are we allowed to call them that)? Their fans are a lot of fun to tailgate with.
I proudly hang my Bills/Sabres flags on my deck, and front porch every year.
