always pay attention! i was taught the same lesson when a snowboareder hit me in the terrain park after i wrecked on a jump (it was mostly his fault though) it ended up cutting my arm in half and snapped through my ski pole. i lost mobility in my hand but it could have been a lot worse! especially if i didn't have ski poles! you can always say you got off lucky when you look back at wrecks, but by paying attention you can minimize having to do that.
