Chicago, what are you curious about? That might serve as the tagline for the WBEZ radio program "Curious City," as it's an inquisitive program that asks its listeners that exact question. The public submits queries about Chicago here on the show's site, visitors vote for the questions they like the best, and then the crack team at Curious City investigates and reports back, complete with help from locals who want to be part of the whole recursive process. On the site, visitors can look over the Up For Voting area, which includes questions that cover everything from Cook County Hospital to the design of Wrigley Field. For complete audio and written answers to questions that are wrapped up, click on over to the Answered & Investigating area. Here visitors can look over questions such as "Will the Pullman neighborhood ever be revitalized?" and "What is the origin of Chicago's distinctive wooden fire escapes?"
