CHICAGO --Should Chicago's children's museum make the move to Grant Park? Navy Pier is the current home of the museum. There's a $100 million proposal to move the museum to a location at the north end of the park. Opponents, including Alderman Brandon Reilly, say Grant Park was dedicated to free and clear space. Reilly points out that the Illinois Supreme Court has ruled four times against construction of buildings in the park. But on Monday, a group supporting the plan claimed access for children is the key issue. "We're the All-Chicago Committee because that's what we are. We represent this entire city. We all believe that the museum should be in a location that is accessible to all Chicagoans," said Phil Harris, former chairman, Chicago's Children Museum, The move must be approved by the city council.
