Season Thirteen of Bonanza began on September 19, 1971 with the series' 390th episode, "The Grand Swing." Young Jamie's carelessness results in the loss of a valuable horse. Hurt and humiliated, Jamie offers to leave the Ponderosa for good. Rather than display anger, the boy's adoptive father Ben Cartwright takes Jamie on a extended pack trip through the length and breadth of the Cartwright property, hoping to demonstrate how best to handle difficult situations. In the course of the story, Ben and Jamie become closer than ever. Highlights of this wonderful episode include a full tour of the Ponderosa spread (filmed in Arizona and California), and a poignant vignette involving a "witness tree", where Hoss and Joe Cartwright's names were carved years before. "The Grand Swing" was written by Ward and John Hawkins and William Koenig. ~ Hal Erickson, Rovi
