On last Sunday's Goose Island / Pulaski Park walk a girl was along recording the event. Turns out she was from WBEZ and here's a link to her article. Turn on the sound to hear what was being said.

All the tours I've been on have been great. Lots of work goes into making these interesting and informative events. Kudos to the FC crew.
