Jason Cesco joined the racks of the few maniacs who have backflipped a snowmobile on dirt this summer. Here's the nauseating stunt from his helmet cam. It's disconcerting to see skis riding over rocks, let alone over your head.
Snowmobiles get repurposed to do all kinds of wackiness. I once saw one hit 170 MPH at an asphalt drag strip in Canada. Winter X-Games are just a couple months away!
