I moved to Chicago right as this scandal happened. There are still problem areas in some neighborhoods, though luckily, not at the Haymarket Station.
Chicago Tribune | A cast of characters in Chicago alley history
Undelivered U.S. mail turned up all over Chicago in 1993-94, a scandal leading to a major shake-up in the postal department here. Adding fuel to this blaze was the discovery of a carrier bag in the alley behind 333 S. State St. In it were 46 unopened pieces from a state government office. A private courier found the discarded bag and reported it to police, who alerted a postal inspection service. This mail eventually got delivered -- a little late -- to Chicago's main post office only a few blocks away.
