Long before everyone kept their eyes down on an electronic device, you could communicate with folks for a mere dime. Or, as Travis Tritt sang about a little later, a quarter. There were no big expenses on communicating. Not as convenient, but a simpler time.
You're going to go back to the time of Ma Bell. A time when you looked for a little blue sign and a little blue booth, dropped a dime in, and waited for your party to answer.
This should be a fairly easy find and gives you an opportunity to see an old necessity of the past.
