I slid down what everyone affectionately calls the 'Death Slide' when I was about 10. During the winter the death slide turns into an almost completely vertical icy hill with a short ramp at the bottom. It also happens to point RIGHT at a shop wall. Oddly enough, the safest way to get down the Death Slide would be to slide on your ass, use anything else and you're almost bound to get launched into the shop. I've seen it happen, not a nice sight.
