Ask Geoffrey: A Special Navy Pier Edition

As Navy Pier celebrates its 100th birthday, a viewer wonders how it has managed to stand up to 100 years of Chicago's brutal winters.

Geoffrey Baer is here to answer viewer questions about Navy Pier in a special edition of “Ask Geoffrey” and to give us a sneak peek at his new documentary about the Pier that debuts on WTTW on Thursday night.
