Very unworried, nonchalant Copperhead, about 3 feet in length. Taken by my wife yesterday at Misty Mountain near Cloudland Canyon in northwest Georgia. She was escorting a group of 10 year-old Girl Scouts on a hike when she spotted it.
The really scary thing is one of the other chaperones told everyone not to worry, the snake wasn't poisonous. Fortunately my wife knows her local pit vipers and kept the kids, including our daughter, well back.
