They had a set which involved a stone wall and a (fake) spring, which is seen in the The Brother-in-Law and in Eight Hours to Die — it is the place where the judge shoots the rattlesnake to save Mark and again in this episode. The Young Englishman — In the very beginning of this episode, you can see that same stonewall that was used so often in the first season. Also in The Angry Man - By the way, the first appearance of the stone wall, which is seen in a number of first season episodes, then never again, is in this episode. I do not think it was used as a filming location anytime after the first season, for whatever reason. I wonder why they did not seem to use that location for filming in later seasons?
