That game is remembered most for the out of control crowd that day. There were so many fights in the stands, the Cubs instituted new security measures. Among them, installing the screen at the top of the wall--to keep the fans from coming onto the field.
Before that was put up, drunken fans tried to tightrope the walls -- and, depending on their alcohol consumption, had a tendency to fall...hard. The reason the baskets are still up is that they have been incredibly successful at achieving their main goal: keeping inebriated fans from falling onto the playing field.
Despite what former ESPN commentator Joe Morgan has said, putting up that screen had absolutely nothing to do with getting more "cheap home runs" for Ernie Banks. Ernie only played one of his 18 Cubs seasons with the screen in place. Joe Morgan should know better.
