thats just how it works. its called a hub and spoke system. http://en.wikipedia.org/wiki/Spoke-hub_distribution_paradigm everything goes through the hub, unless its time critical. if it's time critical, then you would have chosen priority or overnight and it can go spoke to spoke. its not really a waste, because that truck was going to kentucky with or without your package. its not like they made a special trip just for that package. USPS handles more than 500 million pieces of mail every day, im sure they've figured out what works, and know what they are doing lol. in the early days, fedex used to ship EVERYTHING through memphis. if you shipped standard from philly to NYC, it would go from philly to memphis, then from memphis to NYC. again, this is for standard shipping. if you ship overnight, then it can go straight from philly to NYC. nowadays they have a lot more hubs (there's one in grove city) though, so not everything goes through memphis. heres an animation showing fedex's hub and spoke system. http://www.youtube.com/watch?v=CzsXqawswPc&feature=player_embedded
