Heavy vehicles manufactured in Detroit once dominated roads in every part of the world. A few managed to avoid the wrecking yard and now sleep in pastures or beside rural lanes. They have become a kind of nostalgic industrial sculpture to be photographed and remembered. As someone with personal experience of the mid twentieth century I say let them sleep. We of a certain age often insist that our industrial past was a national high water mark. The tools of the past don’t fit the talented hands of the present. Those hands will shape new tools for their world.
