But not Wednesday, when a goat's head was left in a box outside the home of the Cubs. The box was addressed to team chairman Tom Ricketts.
Ricketts is currently in negotiations with city officials and neighbourhood business people about the $300 million renovation of Wrigley Field.
Cubs spokesman Julian Green says staff at Wrigley Field discovered the package and immediately called police.
Chicago police spokesman Officer Veejay Zala says Chicago police responded to a call around 2:30 p.m. indicating an "intimidating package" had been received. Zala would not elaborate, saying police are investigating.
Chicago legend says a restaurant owner allegedly cursed the Cubs when they wouldn't let his pet goat into Wrigley Field.
