"Lincoln Park Zoo is hosting a wide variety of events as part of their annual Fall Fest. Throughout October, you can expect installations and pop-ups with things like a harvest maze, professional carvers making jack o'lanterns, and a pumpkin patch. They also have a few scheduled events like "adult's night out" on October 27, with games, a DJ, and cash bar, and Spooky Zoo, a day where kids can show up in costume and trick-or-treat while checking out the animals." - john ringor
