And a lot of people make that argument. I don't buy it, not for a second. There are NFL cities with more well mannered fans than other cities. Obviously all cities have bad apple but no way I'm buying that in every city it's the same ratio.
I remember well all the games I attended at the Coliseum and Anaheim, with season tickets, seeing every NFL team.... You KNEW who the trouble makers were going to be. I wouldn't take my kids, (who were very young at that time) to a Rams vs Raiders game.... far too risky.
As for Detroit... as I said, no idea what they are like 'typically'.... and I think a lot of the 'bad press' around me is no doubt inspired by the fact that I live in Niner country... still, that doesn't excuse some of the crap I've seen.
