Someone else on the run posted it over a week ago and then deleted it.He posted the link to all the photos.

But yeah, he stopped for a piss break and then was catching up when he rounded the corner and everyone was stopped. 3 choices, left and down the mountain, straight and hit everyone, or right into the ditch and try to stop. If I remember, he said the tires bit on the hill and he couldn't turn back left and it rolled. This is what was posted IIRC.
