It breaks down like this
Davidson county designates certain points like Negley and Shys Hill and the furthest encampments and batteries both sides
Franklin has the historical preservation and battlefield trust which maintain a fair number of sites and lands
Hoods HQ on Winstead hill facing north on Columbia pike south of the Carter house etc is I think maintained by an SCV chapter and the greenway just north of it by the city of Franklin
It’s all broken up polyglot managed and of course run by liberals since they gravitate to such things like polluting algae
Spring Hill and Thompson Station sites are similar run by local entities I think
Stones River or Battle of Murfreesboro is run by the federals
thank you!
