>Buy a trailer, live somewhere cheap, do odd jobs

Unrelated to the discussion, but I love these kinds of backup plans. I've found that most guys I talk to have one. Just a few days ago a guy was telling me that, if his beloved wife ever divorces him, then he'd move to a tropical island and become a coconut seller.

(My personal plan: find a small town in the Sonoran Desert that has a good library, dig a hole under a nice big Saguaro cactus, then live out my days reading library books in my cool and shady cave.)
