The Naperville Jaycees’ Last Fling is a family-friendly community festival that takes place over Labor Day Weekend in Downtown Naperville along the beautiful Riverwalk. This summertime extravaganza has been cherished by our local community for more than 50 years and for many, is the best way to say their final farewell to summer! The Last Fling will take place Friday through Monday, August 30th-September 2nd, 2019.
