Looking for more fun things to do this September? Check out events this September in one of Chicago's "sister cities," Milwaukee. You can also enjoy some time outside, especially since September is one of Chicago's best "weather" months, with a Chicago walking tour or be a "visitor" in your own city and check out some of Chicago's most visited tourist attractions. Chicago also has some remaining free museum days in September, including free admission to the Shedd Aquarium September 12, 13, 19, 20, 26, and 27.
