A happy Brit named Alastair Lee has a website devoted to model trains and model railroad layouts. Every day subscribers to his site receive an email with pictures and video sent to him by model railroaders around the world. The miniature scenery, the tiny main streets and train stations, the trees and mountain tunnels are astonishing for their detail. It took me a while, but I know why men of middle age build these tiny worlds. They are recreating the world as it ought to be. And every one of them, to a man, has excluded the giant graffiti that covers the lower third of all the boxcars in the real world.
