Often cited by fans and critics as being the worst and/or least popular episode in the series.
Matthew Labyorteaux mentioned in an interview this was one of his favourite episodes because it was fun to film.
Laura's observation that "those guys look as much like Indians as the Man on the Moon," though seemingly a joke about her naivete, may also be a knowing reference to Hollywood's history of often casting white actors (in Brownface) to play Native Americans.
The first time in the series we see Albert riding a horse, and the only time we see Willie riding a horse.
At around the 39:30 mark (when Albert passes out while leading the wagon), you can clearly see 2 sets of reins, one set going into the wagon where you can see a person in dark clothing that is actually controlling the horses/wagon.
