I think TJ is spot on with this info. I think the part he is talking about is (and this is in the trailer i'm pretty sure) when it shows a bunch of guys riding down throught the pow, and the filmer is behind them and it's kind of a roller section and there is like 5 dudes bombing it. I think CR went over one of the rolls or a drop or something and Kye came up after him. So yea I don't think it really shows it on film, and even if it did I don't think I would want to see it.
I Know CR was hitting pipe not really that long after the accident, but I am pretty sure he was given the warning that if he hit his head again within a year or two it would be very serious. So who knows, maybe he is just taking it easy still. Neverthless, he was an amazing skier and I am 100% he can still rip shit up like a mofo.
