Lacking much in the way of funds, many preservation groups go for publicity as a means of extending their message, using “Top 10” lists. The Civil War Preservation Trust now lists the battlefields around Marietta (scroll down), north of Atlanta, as particularly endangered. Development in this area—housing and supporting infrastructure like roads and businesses—is rampant. In the late 80s I worked on several projects there, including property now a country club. They incorporated (preserved as required by county laws) several Civil War-era trenches into the golf course, and others were in housing lots and to be protected via covenants (never revisited to see if they actually were).
