I was driving down Washington St. In Gettysburg and I couldn't help but note the pick marks left on historic buildings 150 years after the War. I had to stop & nap a few photos of these riddled walls. Most of the damage is facing Federal positions of the 2nd & 3rd. This leads me to believe this is evidence of continued sniper fire between the opposing lines. Note that many of the shots appear to center around the windows from where Rebels no doubt returned fire. Scars of Civil War urban warfare.
