"Assume nothing and trust no one"
Alpine Code... That just applies to life in general!
Part of the reason I love the mountain I ride is that it's never that crowded and the terrain allows you to avoid people. I'm more worried about trees then people most of the day. Shit still happens though, I know it was a lot more a problem when I used to ride at Kirkwood (which isn't even that bad compared to places like Heavenly). Some skier-lady completely plowed my dad at Squaw Valley several years ago, luckily neither of them got very hurt.
