Arizona filming
Grew up with this series and others. One thing I noticed in the 1959 series is that a handful or so were filmed in Arizona rather than the lot and local areas in L.A. Anyone know more about the Arizona episodes. You can tell by the Saguaro cactus, the tall ones with arms.
It would have cost a lot more, I suppose it was Tucson, which had a cowboy town just west of the city that was used for dozens of western series.
