Prior to this episode (including the episode immediately preceding this one) it was well established that the wagon train originated each year in St. Joseph, MO (the actual starting point of many wagon trains) but in this episode, inexplicably, the wagon train is assembled in St. Louis. Rail and boat transportation was available to St. Joseph and there was no need to travel by wagon from St. Louis, which is 300 miles to the East.
For some reason, Ken Curtis's character Pappy Lightfoot had a really bad voice dubbed instead of Curtis's real voice.
