With a certain lack of elegance, the tour bus bringing us back from the Garden of Eden park takes a sudden and angled exit off the Celestial Interstate, and it is only the lack of gravity, and the even more shocking lack of Inertia that keeps us in our seats, and our luggage in the racks. Down below, the houses of Alamogordo shuffle from one lot to another, using a complex system of under-street, under-lawn rails that allow them to move noiselessly from one piece of property to another. Without even spilling a drop of coffee from the cup on the way to its owner's mouth.     I watched the people in the trees, and Cain, as he left for another planet.
