Have passed through, visited or stayed in every state south of the Mason Dixon line except Delaware -- unless you want to count New Mexico. (Does Southern Illinois and Indiana count?) First time was a drive to visit Sharpsburg, Harpers Ferry and Manassas, many winters ago.
At the time I wasn't aware that I was a damyankee. Of course, places like that live on the tourist, so I'd suppose they're very careful. And they aren't the deep south.
I was interested in nothing so much as seeing the ground and where this or that general had his troops defend or attack. After a while, you can't study the field without deciding which general was the better one, and was this one as bad a booby-head as everyone says? And then we're off to the races. (No pun intended.)
Before that, I lived in Missouri and visited Texas twice. Even when I lived in Missouri, I believed the war was fought in the east. When I think of what I missed!
