This video was shot in June 2009 by Gabriel Bendersk, a talented and able filmmaker from Argentina. Scott Olson, Patagonia Fly Fishers was fishing with his friend, Martin Carranza, a tremendous guide and also owner of some fishing lodges in Patagonia, Argentina and also Northern Argentina. The tremendous power of a bonefish relative to it’s size can only be described as Martin said: “This is formula one!” The music used is symphonic from a Ralph Vaughn Williams symphony. Scott edited and uploaded the video to Vimeo.
