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.

Whose idea was it to have a separate pension program?” WBEZ political reporter Tony Arnold will be getting to the very bottom (and the very beginning) of this politically troublesome system.
