I hear ya. My issue with the OP wasn't with what the fellow in the video did. It was with the 'hope' that his actions ended in tragedy.
I think there is a fine line between being adventurous and endangering others. I think people should pursue and push their limits in all regards. Danger is always a possibility when we adventure. And people that choose their life's work as rescue are pursuing danger themselves... For their own reasons.
I saw this video of Haley's the other day. At no point did I consider what he was doing to be a stunt. Probably because I have read enough about the man doing the action to believe he knows what he's doing. Maybe I should have spent the time to research the fellow in the kayak to find out if he passed my personal perception test as to who is and who isn't qualified to participate in thrill seeking.
Regardless, great video:
