I went to the Cowboy/Pats game and on the walk up to the stadium I have never witnessed and more classless bunch of hooligans than Cowboy fans. They were even demeaning kids ( under 12 ) wearing Pats jerseys.
One as_wipe actually grabbed at my wife wearing her Brady jersey. I heard more cussing there than I ever heard in my years in the military. I have been to a lot of places and usually held that NYC and the NE had the most obnoxious folks, but sad to say as a Texan, Cowboy fans now own that distinction.
