Thanks a lot guys.
I'll start by readin up on those avalanche threads. Putting the bindings back a bit makes a lot of sense too I guess, thanks for the tip. I'm also counting on decent professional guidance from my brother's friend. He lives in Chamonix, and he's been making a living as a backcountry guide there for the last decade or so, so I'm assuming he'll be experienced and qualified enough not to drag our intermediate asses into extremely gnarly territory
Still, I hope I'll come across terrain I'd otherwhise never ride, and from what I read/heard so far, Chamonix shouldn't dissapoint me
