Pie it Forward/OccuPIE is on a mission to deliver free pie to 44 cities between March and October 2013. Look for a large sign that reads "FREE PIE AND REVOLUTION" around 6 p.m. Wednesday near Wicker Park's fountain at 1425 N. Damen Ave., between Schiller Street and Wicker Park Avenue. More information can be found on the group's website or Facebook page.
