Oh man, sorry to see that, hope he's doing ok. Reminds me of a time my best friend and I were sledding, in our elementary school days. It was a VERY steep hill, that produced speed quickly. Apparently the speed wasn't enough, because we thought it would be fun to build a "ramp" 3/4 of the way down. After that got boring, we figured it would be fun to see if we could launch a sled across the path as we were going down, to jump over the sled. Needless to say, that sled wound up making contact with my buddies face, and by the end of the day, both of his eyes were swollen shut. Good ole sledding war stories.
