Here is another Sound Byte from San Francisco and its’ MUNI Metro trains. Listen for the ghostly sound of the BART train (one more level down into the earth), the clink of coins falling into the turnstiles and the tap of shoes heading up the stairs to the street.
Special mention must be made to the invaluable help in creating this “byte” provided by my partner-in-life-and-crime: Danielle Clay.
