One has to wonder what the capacity is that UPS can handle in Louisville, too. I know it's a HUGE hub and they process hundreds of thousands of parcels each day, but when you get that many packages dropped on your doorstep in the matter of a day or so, it's got to take some serious manpower to get that all wrangled and distributed!
Remember, it's not UPS that can't handle the load, it's the federal customs folks. Apparently they're taking their sweet ass time. Not surprising being a federal agency, but that is apparently what's holding us up.
