I Googled him and apparently he is legit. Even if his casting call, to us, is rather humorous. Still I think it would be better if they went around to different survival schools and did a "class" from each one. You know, something like "Surviving Disaster". Something you can learn something useful from. Not some Idiot doing foolish stuff. I know I would watch if they went to different survival schools and showed a "class" from each one. I might even buy the video, if it were done right.
