The Chicago Architectural Club is running a competition for ideas on what to do with the gaping hole in the Streeterville neighborhood thanks to the un-built Calatrava-designed Chicago Spire.
The hole is 76 feet wide and 110 feet deep. Here's what the hole looks like, courtesy of the Chicago Tribune.
My suggestion: turn it into a politicians-only prison, with a big sheet of glass over the top, so people can walk by and gaze down at all the Chicago and Illinois politicians who have been convicted of corruption, tax evasion, etc...Though they might have to dig the hole a bit deeper.
