About this tag

The tagger called this “a joke for the phreaks out there,” and the joke is the address. Engine 18 sits at 2600 S. Fourth Street. In early phone phreaking, a 2600 Hz tone could be used to manipulate Bell System long-distance trunks, and the frequency became famous enough to give 2600: The Hacker Quarterly its name. The firehouse itself dates to 1900, when it opened with Chemical Engine 3. Engine 18 moved in two years later, was motorized by 1919, and is still stationed here more than a century later.
