Stop by the Old West Holiday Pony Express Stop in Cheyenne to deliver your letter to Santa Claus! All ages are welcome to write their letters inside the mailroom (Chronicles Distilling) and get the letter officially stamped by the Postal Elf before dropping it in the mailbox outside on Saturdays, 10:00 am–5:00 pm. A Pony Express rider will pick up the mail twice daily (11:30 am & 3:00 pm) and deliver it directly to the U.S. Post Office, so plan your trip accordingly! During the week, letters may be dropped into the mailbox outside Chronicles for delivery to the North Pole.
