Chicago, New York, Houston, etc. all cities have there obnoxious fans. I got hit by a thrown bottle of Jack Danials coming off the field at Fayetteville (LSU vs Arkansas) . . . whew! . . . still had my helmet on! But hitting a woman at a sporting event is only reserved to the most gutless of cowards and they are not limited to Chicago.
Oakland has the worst fans in pro ball. That is the consensus of American League teams, and even some National League teams.
