The Hashknife Pony Express makes its ride traveling 200 miles from Holbrook to Scottsdale, Arizona, and delivers 20,000 first-class letters by horseback. The ride is led by the Navajo County Hashknife Sheriff's Posse. More than two dozen riders in authentic cowboy clothing carry the mail, relaying the bags along the route. The grand finale happens in Scottsdale, with the ending ceremony at Scottsdale Stadium! This event is part of Scottsdale's Western Week.
