What I’m looking for is the smallest real town or city that has been used as the setting of a TV series, providing that the series was set in the same period it was produced in. (For example, a series produced in the 1970s that was set in the 1970s, etc.)
It seems like most fictional TV series that are set in small towns are set in towns you can’t find on any map, like Cicely, Alaska (Northern Exposure), Mayberry, North Carolina (The Andy Griffith Show), etc. When a small town in a TV series is real, the show is usually set far in the past, like Walnut Grove, Minnesota (Little House on the Prairie), Virginia City, Nevada (Bonanza), etc.
I’m not looking for a small town that the characters may have visited once or twice, but a place where a significant portion of the action takes place, week after week.
I thought of Tuckahoe, New York (Maude), current population about 6,500. I don’t know what the population was during the run of the show in the 1970s.
I also thought of Rome, Wisconsin (Picket Fences). There really is a Rome, Wisc. (population unknown to me), but I’m not sure it should count. I don’t think the producers of the show had the real town in mind when he decided on the setting. I’m willing to be convinced otherwise, though.
Anything smaller? Mostly I’m interested in U.S. places and U.S. TV series, but I’m not a xenophobe, so bring 'em on.
