I'm sixty miles from Memphis and there are sites around but hard to get permission. Germantown, byhalia, la grange, grand junction, Corinth, holly springs, and others.
You will be moving into an old but as far as I can tell void CW area. I'm sure there are some picket stations and old camps in the adjacent counties but almost everything in this county - no kidding - is about paved over - explosive and out of control developer area. All the farms are gone almost.
On the other hand I do have a few ideas but just need someone to go with me - can't go there by myself.
