Chicago Children's Museum

This guide to the Chicago Children's Museum asks why a museum built for six-year-olds signed a lease running ninety years, tracing back to a stalled plan to move it to Grant Park and the deal it struck instead with Navy Pier in 2012. It covers the museum's history since opening at the pier in 1995, and the terms, an initial term plus renewal options, that stretched into that startling span. Listen for it while you pass the dinosaur dig and the tinkering tables.
