    “Own only what you can always carry with you: know languages, know countries, know people.

    Let your memory be your travel bag.”

    -- Aleksandr Solzhenitsyn (From "The Gulag Archipelago")

    Today we explain our collaboration with other education settlements in the US and other nations.  We conform to participation requirements set by ANSI US Technical Advisory Groups to the International Organization for Standardization but we also have liaison with other universities in the European Union who conform to the participation requirements of their own national standards bodies.

    Going Up: Uncovering the Art Deco Elevators of Landmarked Building Interiors

    Architectural Digest: Why The Chrysler Building is a New York City Icon

    Many education communities have 100's of elevators and escalators.   This is a difficult space for driving costs down

    (because of strong manufacturer and labor presence) but we will give the "old college try"
