"Out of the hills of Habersham, down the valleys of Hall" -- ln 1879 when Georgia poet Sidney Lanier wrote those lines of "Song of the Chattahoochee" he didn't anticipate the series of dams and lakes which would interrupt the 'Hooch as it "hurried a main to reach the plain." Of course, that river joins the Flint and Apalachicola before it ultimately flows into bay and gulf and ocean. Those waters, as we know, are still in controversy as they flow -- and of course, Lanier could not anticipate that.
