The Great River Road hugs the Mississippi north of Alton, Illinois, for a serene stretch of some of the most beautiful mileage you'll find in the Midwest. Get on up there and be prepared to fall in love. Or, this weekend, in fright, because it's time for the Evil Forest special event at the Talahi Lodge in the Olin Nature Preserve–The Nature Institute (2213 South Levis Lane, Godfrey, Illinois; 618-466-9930 or www.greatriverroad.com). The trails at the Nature Institute wend their way through southern Illinois forest — ideal habitat for getting the pants/skirt/whatever scared off of you by volunteers dressed in frightening costumes of their own wicked design. This annual excursion through the gloaming starts at 7:30 p.m., wraps up at 9:30 p.m., and costs $10 per person with no pre-registration required.
