I finally got a chance to watch this, and it was fascinating. They seem like happy and well-adjusted people, contrary to what most people would expect.
One really interesting aspect I noticed was how difficult he thought it was while still single to last a single trapping season (Nov-Mar) alone. Makes me think of the recent WSS thread on how long you could last alone in the wild without people. A lot of us probably overestimate our ability to be alone.
