I have lived in my current house for 10 years and 9 months. In all that time, our mail has been deliverd by a nice man in a station wagon. In the last few years, he upgraded to a Saturn Vue. Although I live smack in the middle of a major metropolitan city, my mail is considered a "Rural Route."
Today, I saw that same nice man delivering our mail in a bona fide United States Postal Serive truck!
He must be so excited not to be putting wear and tear on his own vehicle.
