Rob, don't feel too bad. I live less than 12 miles from the main PO in Macon, less than 10 miles from the Walnut Street branch in the Federal building, and less than 5 miles form the riverside branch PO. It still takes 4 days to get a piece of mail that originates in Macon, delivered to my house.
USPS service is POOR, at best, and they are bleeding money, too.
