HORRIBLE US Postal Service story, btw. Abominable.
Just for comic relief, I have a little USPS story of my own that's not even a week old.
A friend and I drove from here to Orlando (we love car trips), making a number of stops along the way there and back. I'd never seen the very deliberately kitschy tourist attraction "South of the Border" before that, and had a great time exploring it and sending out some postcards. On the return trip I sent a few more postcards from Richmond, VA. One of them happened to be to someone I'd sent one to a few days prior.
That trip was in September 1998. My friend's two postcards were delivered to her on July 16, 2012.
