THE TRAIL TO TOMBSTONE , 58 min. Doc Holliday’s trail to Tombstone began with his friendship with Wyatt Earp and traveled by way of the Arizona Territorial capital of Prescott, where he was acquainted with Acting Governor John Gosper—and may have become part of a covert government plot to stop a threatened war with Mexico by corralling the Tombstone cowboys. In an interview with author Victoria Wilcox, historian Dr. Gary Roberts details the events that led to the shooting known as the Gunfight at the OK Corral and made legends of Doc and his friends, the Earps.
