Took this back in 2010 when I went to Gettysburg with friends. I was just taking pictures out at Devil's Den and when I went through these I had found what looked like a figure out in the brush. At the time I took the picture nobody was out there or even walking near that area of the field. You be the judge.

Interestingly I've seen other's photos of supposed apparitions out at Devil's Den and they looked somewhat similar... appearing human but washed out.
