Wouldn't you know it, but according to satirical weekly The Economist, one of the bin Ladens is building two cities in Yemen and Djibouti, with a 17 mile bridge linking them across the Red Sea.
This is an excellent idea. There are not nearly enough "twin cities" in the world. There is, of course, the very famous Banff-Macduff pairing in Scotland, and that one that ends in Saint Paul, somewhere in America.
It makes you wonder why people don't make things in pairs more often. Twin airports, for example, linked by a motorway (so that you wouldn't have to fly from one to the other). Or twin oceans, separated by a 17-mile landmass. Or even twin people: two babies born at (more or less) the same time. The possibilities are endless.
