Other mistake: Gene enters his ranch house and tells Pat, "I picked up a letter for you at the post office - special delivery." A special delivery letter would have been taken to the addressee upon receipt. It would not be left at the post office.

Visible crew/equipment: As Gene and Pat ride into the yard of Elaine Castle's ranch, the shadow of a crew member can be seen on Gene's horse Champion. (00:07:40)

Continuity mistake: The episode opens with a close-up of a poster saying "Elect John Nevers Sheriff" and the shadows of several branches across it. In the long shot, the branches are blowing in the wind. The opening shot is obviously a still photo. (00:00:38)
Other mistake: Pat, riding a wagon pulled by two horses and headed to Rock River, slows to look at a sign. The sign, shown in close-up, says "ROCK RIVER, 5 MI." An arrow points to the right - but that is the direction Pat is coming from. The arrow should be pointing to the left.
