The real Old West was once alive in Southern Arizona. Tombstone, the site of the real-life “Gunfight at the O.K. Corral,” is one of Arizona’s most popular attractions. Countless Hollywood movies have been filmed here along the rustic boardwalks, against rugged mountain ranges. Reminders of the untamed frontier—the railroad depots and mines, saloons, jails, gunslingers, and dance-hall singers—can be found in real towns throughout Southern Arizona.
