“On a clear day, the sun sets behind this fabulous tree in Lancaster County, Pennsylvania. But on this day, after a light snowfall, the fog rose quickly, and I was able to catch the moody light on the Amish buggy,” says McWilliams, a graphic designer from Havertown, Pennsylvania. “This photo came out exactly as I had envisioned it, which is very rare, as any photographer knows. This tree is one of my favorite subjects. Sometimes I worry that it will disappear, so I try to enjoy it while I can.”
