There isn’t really much to identify this location other than a small building on the property which can’t be seen too well in the scenes from the show. However, this empty field is located on Rising Star Road just northeast of Haralson, GA. It is roughly 6-7 miles from Senoia, which is doubling as Woodbury this season.
Thank you to Tony for the photos of the ambush site.
