On a crescent of paper-white beach along Florida’s gulf coast, the sun catches slivers of sand in trillions of tiny sparkles so that the powdery strand looks as if it’s frosted with sugar. The water is warm, the breezes are cool, and the vibe is bucolic, barefoot simplicity. This is St. George Island, and it is not merely a beach escape as much as it is a peaceful and quiet sanctuary for the mind and soul.
