““[A]s my breath begins to quiet in the silent woods, I pick up a squeaking, creaking sound, growing steadily louder, that makes the hair stand up on the back of my neck. I snap my head up and overhead, oh my God, here comes three hundred, five hundred, a thousand Canada geese, maybe fifteen hundred, stretching across the sky in a succession of vees. Largest flight I’ve ever seen. Underlit from reflection off the snow, a skyful of silver arrowheads, bound due north for the summer to come. A skyful of physiology, riding the physics of the air toward the pole. Riches, riches, everywhere, just for the paying of attention.””
