The true adventurer would throw a mattress or two at the bottom and simply LEAP off the top stair. :D
Sleeping bags were also superior on ice covered slopes. The waterproof material let you get some crazy speeds going. Until high speed adventurer met immovable object ( trees ). Was a short lived plan.
How I lived through my childhood is beyond me. . . . .
Did that too. We would throw the toddler and crib mattresses to the bottom of the stairs and hang over the banister at the top and drop... it was a good 12ft drop.
We also would wax the bottom of our sleds in the winter, or the best ever was getting these GIANT heavy duty plastic bags ( they were like 100lb sugar bags from my dad's workplace ) and we would climb in them and go down the hills. I lived on 3 acres and my dad would plow the snow into a mountain almost as tall as the house. We would tunnel and hollow out the center like a club house with slides and emergency exits. Strong enough to have a full grown Black Angus Steer standing on top with us kids inside.
Or sitting on wax paper at the local park on the slides to make them faster.... Oh my... Amazed we didnt kill ourselves. Swinging from ropes in the hay loft of a barn over a hole in the floor to drop bails through.. Yea we lived! No video games back then.
