That looks so fun!
It makes me wanna grab my skateboard and go cruising, I'm too old nowadays to try for big air, but I used to be pretty gnarly, that feeling of sustained antigravity at speed is exhilarating.
I thought when my pals and I did this last summer that it was crazy.. https://vimeo.com/73663517
It was honestly intimidating at the top, looks a lot steeper when you are contemplating if you're going to end up with a face full of sand or actually make it into the river.. :D
Indeed entertaining, however a famous web fake. The thought of someone actually attempting such a stunt makes me wince. Reminds me of a rather foolish escapade when I was a young teen. Some friends and I used a car bonnet to ride down a mountain of snow. It ended really very badly.
