The reason FedEx packages goto Memphis (at least originally) is because it's the most efficient way believe it or not. The founder looked at a map and realized that if the country was a flat piece of cardboard and atking into account population, it would balance on the tip of your finger at Memphis, TN. It's more efficient to have a central point to sort packages going to one destination than have lots of pages sent willy nilly direct to their destination.
