Jordan - I have never gotten violent over a ballgame. If it was a cards/cubs game then I am almost 100% certain there was beer involved! But to say there is tension would be an understatement. I am showing my age here, but I still remember Ozzie "the Wizzard of Oz" Smith doing his back-flip on the infield as he took his position at short. My first cubs game at wrigley was against the cards and my dad pointed Oz out so I was ready to watch him and his back-flip. He never was much of a threat with the bat, but damn could he flat out play D at short!
As for the NFL - well there are far too many fair weather fans in my area to have ever really held my interest. Win and people love you - loose and all they do is criticize. It was interesting watchig the colts and Manning part ways around here. Talk about people wanting to have their cake and eat it too. I don't mind the NFL - I think the colts being in Indy helps the local economy, but I am not going to loose sleep if they ever decide to leave town.
