Snowboarders have been the most endangered, by me, and the most dangerous to my kids. In every case, it's been the snowboarder (novice) deciding it was time to arch back, and head up-hill on the slope behind them - the same slope I'm arcing down before hopping onto the cat-track or right into my kids snuffling along.
One particular incident - I was coming off Sam's Alley run at Schweitzer Basin, Idaho, to hit the midway loading point they had - a snowboarder decided to use the hillside to slow down on by just turning uphill towards his blind side, thereby intersecting with my 40 mph arc.
Blam! I spun around a few times, losing one ski but remaining standing (Salomon 9E 207cm + Salomon 900 Equipe), while this guy was spewing gobs of blood all over the cat-track. Just GOBS of it. He was laying on his back, screaming, and freaking everyone out; I slammed the other ski off ran over and saw what he was screaming about. It turned out he'd nearly bit a quarter of his tongue clean off - it was hanging by just a few thick (thick enough to retain the bitten-off part) pieces. He got up, regained his bravado and told me to buzz off. He'd spit an entire mouth full of blood, curse at me, but knew it was his own damn fault. That part of the cat track was a bright dark cherry red that day.
I didn't run off. I was prepared to accept responsibility and defend myself from any potential lawsuit. This happened about 12 years ago, and I'm sure he thinks to this day real hard every time he's about to just turn to his blind-side without looking!!
Wait -- you collided while overtaking him from behind and uphill?
