One thing you did not mention seeing was the Andersonville Prison, cemetery and nearby POW National Museum located in Andersonville, Georgia about 100 miles south of Atlanta. Andersonville also has a small ACW museum wirh donation as an entry fee. My wife and I visited all of these 2 years ago in Early December. It was a very slobbering experience. The little museum had a 1/72 (maybe a bit smaller) small scale diorama as well as artifacts from the prison and the war itself. We watched an episode on America's Prisons just a couple of weeks ago on the History Channel and it was all about Anersonville Prison.
