Most likely bear. There have been bear in Hogansville, Ga. south of Hotlanta, and in my Troup County, as well as several killed on I 185 near Columbus. Since they are apparently migrating from two directions, it's likely. I saw a small one several years ago in Troup. DNR said not a bear, so I asked what would happen if I shot the not a bear. He mentioned jail, fine flogging, etc.
