"I am reading 'The City' by Dean Koontz. It is a wonderous story of a child in a big city in the late sixties. The spirit of the city has appeared spoken to him. Mr. Koontz mentions a telephone answering machine. Well I was born in 1960 but hadn't heard of them until well past 1968. I was eager to look up facts of this. In from Cleveland, Ohio. I realize bigger cities most likely had increasingly modernized machines and tools before lesser ones. "
