Image of boy flying off a tire used as a toboggan for sliding. Annotation reads: "Marco Mastrella (13) becomes airbourne after hitting bump in Cedarvale Park." Related caption reads: "It doesn't take a trip to the sunny south to bring winter happiness to youth. All the boys, above, needed was a detour sign - a ready-made sled. Even a discarded tire, below left, can be fun - if you can manage to hang on. Venue doesn't matter, either. There's as much competition on the ice rink created by bulldozers at hHightway 401 near Morningside Ave., above left, as you'll find at Sapporo during the winter Olympics.
