Are you out of your ---SOAPDROPPING--- mind? the time will come eventually when the stadium is not structurally viable anymore. At that point, the team has to decided between more or less gutting the current stadium and rebuilding or starting from scratch at a different location. If the Wrigleyville neighborhood people start up about construction noise, etc., that's when you tell them "have fun with your plummeting property value, cuz we're outta here."
