In a rarity for this series, the Deadwood saloon is a completely different set. Since the Medicine Bow saloon was also featured, it would have been painfully obvious if they'd try to redress it, as was normally the case with "out-of-town" episodes.
William Shatner and Doug McLure would work together on a series in 1975. It was called Barbury Coast. It lasted 1 season.
Contrary to the cast list in IDMB, Diane Roter was not in this episode. She did not join the cast until episode #7 - Jennifer.
