Editor's note: We created a illustrated interactive presentation that explains where bats hang out in Chicago.
Curious City is a news-gathering experiment designed to satisfy the public's curiosity. People submit questions, vote for their favorites, and WBEZ reports out the winning questions in real time, on Facebook, Twitter and the timeline above.
This round's winner is Rory Keane from Chicago's Rogers Park neighborhood. He wonders: "Just how many bats live in the Loop? What are their favorite hangouts?" Curious City's lead producer Jennifer Brandel and intern Logan Jaffe will be dusting off sonar gear and finding guano-resistant clothing to find out.
