As a kid, I was at a snow park, getting towed up a hill in an inner tube. The tube was attached to a cyclical line with spaced out hooks, towing all the tubes to the top of the hill. But mine got unhooked when I was almost at the top and the tube flipped into its side, rolling sideways down the hill. I was still inside, holding into the handles, tumbling end over end but rotating too fast to fall out. The employees looked nervous when I reached the bottom of the hill, no doubt worried that I was injured and my parents would sue. But I just got up and went to the back of the line to go back up to the top.
