Havent done that yet, but I have mountain boarded (Basically when you skate board down a mountain on a skate board with off road wheels), and Scree ran (where you have a fairly steep loose gravel slope which you run and jump down)...I Guess I missed the idea of a ball of safety XD.
I've seen mountain boarding, no thanks.

I did nearly crack my tail bone XD...Going a pretty crazy speed, hit a rock, board kinda flipped....fell first point of contact with the ground was the tail bone...pretty much after I stopped was imobalised until the radiating pain went away. So yeah wouldnt rush back into that one, but most other adventure sports I still would. I love NZs rockclimbing.
