I just clicked over to one of my usual haunts at unofficialnetworks.com and came across this video
showing the area the MS was skiing at the time of his accident. I have to say that this terrain is not nearly as dangerous as has been reported so far, except for the presence of the random rocks that are exposed (which usually means some are not exposed as well). It doesn't minimize his abilities or the extent of his accident, but it does show this was a simple accident and he was unfortunate to have smacked his head so dramatically. Get better soon Schumi!
