That mid '80's episode got right on my tits. Here we were, one of the first countries to convert totally to diesel (and american ones at that), and they deliberately go out of their way to make it look like a 1940's timewarp. At least the Quiet Man had the good grace to be set in the 1920's.
And of course we won't talk about the episode of Mission Impossible set in Ireland, softcaps, grandfather shirts and a green white and gold stripe down the middle of the bar floor to seperate the "tribes".
