It’s kind of amusing how most western shows present a nice orderly town, and hardly anything changes. It’s like they are in some never-ending period of “the west” that goes on forever. You would think a long-running show would depict the introduction of modern inventions like automobiles, electricity, motion pictures,etc. But they never seem to advance from a period of “not long after the Civil War”, even if the show runs for 10 or more years. I still enjoy watching old 50’s westerns.
Richard Boone as Hec Ramsey was set in the early 1900’s and showed the transition from the Old West to the 20th century. Good show. Ran from 72 to 74.
James Garner had a one-season show around that time called Nichols that was set in a similar time period.
