Not at Wrigley it isn't. Not at most ball parks in fact. I don't care where it is. If a fan wants to keep a homerun ball the other fans shouldn't try to pressure or threaten him to throw it back. Then dont go to Wrigley. Every place has its traditions and pressures. Just because it has gone on for a long time doesn't make it acceptable behavior. who cares what other people in Wrigley say/think? if you want the ball, keep it. if you want to throw it back in the spirit of Wrigley, go for it. that man made the decision...he certainly looks old enough to be accountable for his own actions/emotions. Well said, puppet. I'm obviously kidding.
