Fall in Chicago is in full swing, and October's event calendar is filled with some of the biggest events of the year, including the annual Chicago Marathon and the Chicago International Film Festival. When you're not cheering on runners or watching an exciting flick, you can see famous folks in conversation during Chicago Ideas Week, witness a creative parade down State Street at Arts in the Dark or dress up to attend a Chicago Halloween party. Plus, the Lyric Opera's new season has begun, a gigantic Andy Warhol exhibition is opening at the Art Institute and Madonna is headlining a seven-night stand at the Chicago Theatre.
