After taking this photo 3 years ago risking my life :p and camera, I always wanted to do more shots similar to this. I was hanging half way out the window the whole ride down the trail taking photos. No camera nor man got hurt in this shot 
Tanks to Chase Jarvis podcast I got lots of ideas to do just the same stuff without risking my life
Of course the camera is still at risk but its also easier to replace.
Thanks for sharing your techniques Chase
