When cars were invented, the US Postal Service said goodbye to animal-powered deliveries forever—or did it? There's one town in the States that still receives their mail by mule! Meet Anthony Paya, who leads a train of mules on a daily three-hour trek down into the Grand Canyon to bring mail to the townspeople of Supai. Full of authentic Western details about Paya's one-of-a-kind job and magnificent workplace, this beautifully illustrated journey will fill readers with wonder and respect for this unique American landscape. Back matter includes further information about the hazards of working this mail route and author-illustrator Craig Brown's journey with the mule train to Supai.
