By the way - if you haven't gotten there yet, Andersonville is a nice day trip from where you are. The Confederate Naval Museum in Columbus would be a somewhat harder day trip. Savannah, Darien, Brunswick and St. Augustine would be more likely weekends. On a wildlife note, the Okefenokee swamp tour at Waycross is worth the trip, and I think there are supposed to be some bald eagles along the Flint.
We want to go to the 8th Air Force Museum in Savannah, it looks really interesting, we've passed Andersonville site a few times in our travels between GA and NC.
