We got up early Thursday morning to a thick fog covering the battlefield, so we decided to get out for our walk and some fog pics. This one I got near the so-called Peach Orchard, where some very heavy fighting went on during the battle. Crossing fences like these became a very dangerous enterprise. The fog gave me some idea of what it might have been on each day of the battle.

PS - Crop, snap contrast a bit; minor sharpening, sepia toning. (Actually done entirely with Aperture.)
