Glenn Campbell recalls his recent visit to Bulgaria, the world's fastest shrinking country. Since the fall of Communism, Bulgaria's population has dropped by 1/5th, from 9 million to 7 million. The loss is felt mainly in the countryside, where there are many abandonned buildings to explore. Urban areas like the capital Sofia continue to remain vibrant, due to a phenomenon Glenn calls "the Grand Hotel Syndrome": When a large hotel loses guests, management closes off wings and floors.
