to clarify about chamonix; don't get me wrong, the terrain is mental. this place is where extreme was born, and they were doing it 50 years ago. if you stop by the mountain rescue/police HQ, you'll see a memorial to all the rescue guys that die on the mountain, and there's pretty much 2-3 a SEASON, let alone all the tourists.
so, it's insane, but almost TOO insane.
