I took this picture about ten years ago, while on the battlefield at Cold Harbor. You see that gray hazy area around the middle? I am not saying its a ghost or it is not.. I don't know what it is. I didn't see it when I took the picture, only after it was developed. I wasn't smoking a cigarette at the time, so its not smoke. And there was no fog. It was a clear day, midafternoon. And it doesn't show up on the negative.
I have always wondered about it. You be the judge.
