A group of insane Germans – ever the productive demographic – have built the world’s largest model railroad in Hamburg as a tourist attraction. Not only are there trains running through the massive display, but also cars and other vehicles. They even meticulously modeled an airport complete with planes taxiing, taking off, and landing. As a helpful reminder that we puritan Yankees didn’t build this marvel, there are also people randomly having sex all over the place. Well done, Europe.
