Signs of New Imagination

25 Jul

Born in the era of punch cards and vacuum tubes, I marvel at technology’s keen ability to accelerate its own growth. As we embark to create new trail signs in Franklin and elsewhere, digital breakthroughs are leaping their way onto our old placards. Take for example Fort Granger, the Union Civil War Fort at Franklin and the object of my dissertation. For students and tourists, the best we could do in the past was to show this geometric jumble of a two dimensional map.

Granger, with its bastions and moats, set upon a treeless and barren landscape, towering above the Harpeth River, just as it once did at the height of the Civil War.
