A coalition of community groups has come together to oppose the Chicago Bears’ plans for a new lakefront stadium. The organizations planned to gather Wednesday outside Soldier Field to call for a halt of plans to build a new enclosed facility just south of the current stadium. The gathering is led by Friends of the Parks, the nonprofit group that waged a successful fight against the plans of Star Wars creator George Lucas for a museum on the same site. Friends says that dozens of groups representing the city’s racial, economic, civic and geographic diversity have come together to announce their opposition. Participants include speakers from the People’s Council of Southeast Chicago, People for Community Recovery, and Landmarks Illinois.
