I live deep in southern Civil War history country with some fabulous historic plantations and battle fields. About 20 minutes south of us is historic Franklin that is a must on any visitors list.
A piece of trivia. During the Civil War one of the major battles was fought by Scots on both sides.
Here's an interesting read about Scots and Scots-Irish influences in historic US of A. http://www.visitdunkeld.com/scottish-americans.htm
