Are you (or have been) a skier? This clip from CNN includes 'helmet cam' footage. "Oh, S**T!"

All I saw was a commercial at that link.
The ski run appears after the commercial.
I dislike having to tolerate the commercial too. Perhaps that is how they pay for their 'news'...
"The scariest thing I've ever done."
I was driving a truck, at night, across a frozen lake when we hit open water, put the hammer down and kept going. Fortunately it was only water on top of the ice, under the snow. There was about 2 or 3 feet of ice and the weight of the snow pushed the ice down, causing it to crack and let water up onto the top of the ice. Couldn't tell it was there until we hit it.
Many years ago but I still remember it, like it was yesterday.
