This is the only episode of the series where Heyes and Curry share no screen-time togethee.g.(although both interact with the female lead, Diana Muldaur. Heyes appears in appx. 2/3 of the episode and then narrates a flashback, wherein Curry first met the lady). The reason being both Pete Duel, and Ben Murphy were each busy working on other series episodes where they mostly work separately from each other, and the filming schedule and script were altered, enabling 2 crews could film each of them, enabling them to complete 2 episodes for broadcast. (Except for "The Ten Days that Shook Kid Curry" in the third season, in which Curry's kidnapped, and Heyes must track him down, the 2 would never spend significant time away from each other, again.)
Several names on the board listing the horses in the races depict various names from the Old West (i.e. Sun Kid, Billy K).
