One time I was like 12, I was cruising pretty good on a straight groomer and I sat down on my tails and put my poles straight forward over my noses. After I had my fun doing that I stood up, but as soon as I moved one of my poles dug into the snow and the handle hit me in the face breaking my goggles and I think I got a bloody nose. Luckily, I was not yet addicted to stylish and expensive eyewear so all I lost was a 15 dollar pair of scotts.
