You really, really want to devote as much time as possible to visiting as many places as possible during Open House Chicago, October 15-16. Check out the roster of “200 cool places” at http://openhousechicago.org/sites/
Plan your days by location, history, architecture, culture, interior decor, exclusivity of access, or whatever. Our recommendation to many folks we know is Sedgwick Studio (“Enter through alley, use red door”). These are pictures from last year at that location (as ever, click on pix to enlarge ’em).
