Well I'm certainly glad Alan won. My wife and I were rooting for him. Shows you that maturity and a sense of humor are important.
I find it very amusing that because the participants were all given two tarps before they chose their ten items someone posted that they were simply doing "rough camping."
The casting videos for the participants are up on the history channel youtube channel. Alan has a youtube channel called AK Guardian, and Mitch has an excellent channel called native survival. I was familiar with Mitch through his channel for awhile before he was recruited for Alone. I presume that some of the participants were found by the producers through their channels.
