SO and I have a theory, evolved on a cross-country drive, that every day the sets are built, and then torn down and built again to simulate reality for us. Whenever we saw road crews, we'd say 'Aha! didn't get started early enough!"
Then we met Neil, who was a solid 24k nutter. He believed (among other things) that yes, the moon-landing was faked, and also, that everything in this world as we know it is actually artificially constructed, deep under Antartica. We laughed, but the man paid our rent for two solid years (we were doing flea markets at the time and he would buy anything having to do with the New York Mets, the 65 World's Fair, the Seattle Space Needle, and I forget what else. Oh, and he had a trust fund, and never had to work a day in his life.
He also ran for president in 2000 and 2004, I wish I could find the websites, they were hysterical. Think 'Aliens under Denver International Airport' and you'll have most of his platform.
