CHICAGO --An effort to save the Swallow Cliff toboggan slides in south suburban Palos Township made its way to the Cook County board Tuesday. A group opposed to razing the slides boarded a bus Tuesday morning for the trip to the Cook County building. They joined Palos Park Mayor John Mahoney who made an impassioned plea to commissioners to save the slides, known to many South Siders as "Terror Hill." But in the end, the board voted to demolish the slides. "I hate the idea of demolishing these slides along with the piece of history that would go along with it. But the area to be used as a sledding hill will raise the activity in Swallow Cliff that they haven't seen in years," said Elizabeth Gorman, Cook County Commissioner. They did leave open the possibility of rebuilding the slides, pending a viable proposal. For now, the plan is to turn the site into a sledding hill, which costs far less to maintain.
