My family and I attended the 150th anniversary of Gettysburg. It was very hot with a threat of an afternoon/evening thunderstorm in the forecast each day. On the third day, during the reenactment of Pickett's charge, very dark and ominous storm clouds gathered. Fortunately the rain and lightning held off until after the reenactment. We returned to our campground and when the rain let up a bit, we went up to the area of the battlefield known as the "Highwater" mark where the Confederate line breached the Union line. The clouds were still very dark and heavy, with a little light rain falling. As I wandered along Hancock Ave. I approached a photgrapher. He had his camera mounted on a tripod (with a rain cover) and was using a neutral density filter/long exposure to capture the swiflty moving low cloud cover. I said "Hi", he looked and then grumbled at me. I said "Clouds are really moving," he grumbled again. I wished him luck with his shooting, and he grumbled something back at me as I walked away. I chose to go in the opposit direction of where he was standing. I walked to the highwater mark area. As I came up to a row of cannons, the sun suddenly broke through the heavy clouds, producing an absolutely stunning sunset and with an interesting refelction on this one cannon. This lasted for only a few moments, but it was pretty spectacular. I suppose I should thank the grumpy photographer, as had he been the least bit friendly, I would have missed this shot.
