@pollick, I remember all of those sleds, but you have to admit the king of the hill was always the Flexible Flyer. You could steer it with your feet, or if you were really daring, you could steer it with your hands while your head led the whole way down. We'd rub wax on the runners and it would really fly.
I didn't see it in the article, but we used to have toboggan runs at a local park. They were wooden chutes filled with snow, and riders would rent a wooden toboggan and slide for at least a quarter of a mile. Sometimes these chutes would end on a frozen lake.
