Went in 2009, my advice is don't do it. Fans are horrible, threw rocks at us, people tried to fight us after we won, horrible Katrina jokes, etc. Other than the game, Buffalo and Niagara Falls were fun
They are among the worst and most angry football fans in the NFL. I went last time we played there. Men called my 9 year old names and threw beer when they started losing. The city of Buffalo is pretty crappy too. Niagara Falls is nearby and it is beautiful, on the Canadian side especially. Also, central New York in the fall is 2nd to nowhere in the world in late October.
That said, I'm in if we are meeting there. We can stay in the Falls area and drive to the game for those staying a day or two.
