I remember the sign(s), but never heard much about the show. We frequently stayed in cabins at Kimberling City, and "Branson West" was just the 13/76 crossroads back then.
There was a supermarket and liquor store in Kimberling directly across 13 from the cabins. When I started college in '81, I dated a girl whose dorm suite-mates were sisters, and their family owned those stores. Small world! Man, wish I could think of their names, and the name of the store... one sister's name was Marla.
