When dad got a job at Lockheed in Marietta GA we lived practically across the street from the entrance to the Kennesaw Mountain National Battlefield Park and a place called Kolb's Farm where a battle took place. I found grape shot, what we called minnie balls, bullets, shell fragments and a part of a belt buckle while raking the yard. Dad decided he should take them so I would not lose them. It was nice of him to lose them for me. I have no idea what became of them or the arrowheads, spear points and pottery shards I also found.
