Best 60s-80s survival tactic was, when airborne head first, the quick tuck, take the landing on a shoulder and don't fight the roll. Came in handy with metal wheel roller skates & skateboards being towed behind a kid on a bike. Careening down steep, dry grass hills on cardboard toboggans also launch worthy. Best workaround to the metal slide of pain? Haul a 3-gallon bucket of water to the top. Ka Zang.
