That's a shame. I am sure there was so much virgin snow and space for both of them to experience a fantastic ride on the same moutain, without ending the day at hospital.
The best thing to do is what I do : I go to places where I have never seen any other skier, just like in this secret place yesterday and the snow was powdery and untracked.There are so many remote places in the Alps where you don't see tracks. I know quite a few in my area and they are always deserted because ski-tourers think that there is nothing interesting to do there.
