My avatar is my best dog buddy, now deceased. His name was Arthur. When my oldest granddaughter first saw him she said, "Arthur? He look more like and 'Arfer' to me!" His nickname eventually morphed into "ArfieBoy!"
Seek permission to detect private property. I don't know about the laws on detecting public land in Georgia, but there a lot of people on here from Georgia. Maybe some of them will chime in. Good Luck!
