Great post David. The lack of parity in the application of the National Register is reason enough to give it time to grow and overcome past oversights. The corporate vermin who are attacking it and the protective process are concerned ONLY about bucks in their pockets over the next four quarters. This venality is encouraged by the so-called "moral" leaders of our political institutions at the moment who also short-change education to separate all americans from their history. As a footnote, in North Carolina, and south through the pine forests, the dirt rims of the "boil-off" rings of turpentine production are commonly found as silent witnesses of the naval stores industry, manned first by slaves, and later by "free" blacks which was one of the economic backbones of the south, even after tobacco and cotton ascended. Don't bother looking for artifacts -- those who built them had nothing to leave behind. Tim T.
