Last month, during my recent trip to Mexico City, I wrote that I sent a postcard to my cousin up here in Ohio. I did it as an experiment to see how long it would take for my cousin to receive it. I sent the card on November 13th. Yesterday, December 18th, it finally arrived in the mail. That's 35 days to deliver a postcard! You can see why many years ago I gave up on sending anything to or from Mexico via the postal service.
