So next week I'm going out to Chicago for the fifth time in as many years, since my girlfriend's family lives in the area. I've naturally seen all the big sights (Wrigley, Sears, Field Museum, Navy Pier), and a lot of the less famous ones (Robie House, U-505).
I love Chicago, and I know there's a wealth of interesting things there that I haven't seen. Any Chicagoan FOTs have any suggestions off the beaten path? I don't want to force myself to endure a 'Wait, Wait, Don't Tell Me!' taping, 'cuz that's all I got.
