A trip to Navy Pier always promises a day of fun; but this summer, Chicago's No.1 tourist attraction ups the ante with a brand-new, 13-acre green outdoor space that's packed with amazing (and free!) programming. Polk Bros Park will now serve as the Pier’s gateway and the city’s unofficial front yard. Two performance and picnic-friendly lawns, located at the south end of the park, will offer free arts and cultural programming throughout the summer and beyond.
