I went snowboarding with my cousin for my birthday. I had a blast and hit the terrain park everyday. At the end of the last day, during a night session, I ended up slipping off a box and smacking my shin on the metal coping. The friction melted a part of my pant and skinned a part of my shin under the pant, through my thermals. The bone is now much thicker in that spot than the rest of my shin.
