Not that anyone wants to think about winter after this glorious weekend, but the Swallow Cliff toboggan slides (also known as "Terror Hill") in Palos Township are in danger of demolition. The mayor of Palos Park and other concerned south suburban citizens want to preserve the slides. Those with happy childhood memories of sliding down the slope at 65 mph under the constant threat of contusions, concussion, and broken bones are invited to contact the Forest Preserve District of Cook County and protest.
