In which state does the United States Postal Service regularly deliver mail by mule?

The last USPS office still receiving regular deliveries by a team of mules is in the small town of Supai, Arizona. The office is located on the Havasupai Indian Reservation, whose residents live at the bottom of a part of the Grand Canyon.
