Earlier I looked at a somber Christmas episode of Dragnet. Another radio program from the same era which also strived for realism was Gunsmoke, but their Christmas episodes are feel-good programs. And so it is with the one I've chosen from December 20, 1952. It features Marshal Matt Dillon (as played by William Conrad) trying to get home to Dodge City for Christmas by hitching a lift with a very taciturn man. As Dillon tells his new acquaintence what Christmas is like in Dodge he gradually begins to win the man's friendship.
