Character mistake: When Hoss takes Timmy for a horseback ride, after they both dismount by the lake, Hoss calls Timmy by his real name Johnny (Whitaker) and not Timmy.
Factual error: The show is set in the 1860s. However, in several episodes, trail boss Gil Favor can be seen wearing Wrangler jeans. The Wrangler brand was not introduced until 1947.
