So there is a story to this clip. On the first day of our roadtrip we wanted to shoot some rockgarden footage with my high-speed cam. And so we did, from several angles, all was good and dandy - so we started to experiment some more - with camera placement in particular.
I asked Christian to to ride past this stone field, with close proximity to the camera. He did so, what he didn't tell me was that he decided to block his rear wheel to "make stones fly". So there he went, blocking his rear wheel, kicking up stones, some of them where pretty big, like in hand-size big, and just as he did so, I saw them coming full force in the direction of the camera, I remember thinking; "There goes my cam".
For some lucky reason the stone missed. The camera was a inch from destruction, but hey, they footage turned out sweet. Watch the stone at 22 sec.
