Oh shit, we have tons of kids and filmmakers coming into the area on September 17th! The Oak Park International Film Festival is happening on that Saturday starting from 9 a.m. to 1 p.m., at the Oak Park Public Library and the entrance fee is zip (free). So the area is going to be filled with pedestrians, bikes and cars this is just a heads up in case you did not know and planned to be in the area at that time. Oak Park, Il is great for not promoting such events instead letting people try their damnedest to navigate through such traffic nightmares as this is going to be.
If you are interested in going or just want to avoid the mess this article has more information about the Oak Park International Film Festival:
