When you need to get away from it all, there's no better escape than to the suburb of Lisle, Ill., home to 1,700 acres of picturesque rest and relaxation. You can discover this rare and unique area just west of Chicago along innumerable footpaths and trails, or you can follow one of the paved roads through the park in your car. Unfortunately, you can't take your car through the hedge maze. That would be cheating.
