The first inkling Frank had of the change that would overtake him came on the drive down. He was in the back seat, his hip aching from hours on the Interstate, listening to a radio show about snow geese migrating from the Arctic, big flocks miles high but always along the same route: migration corridors they called them. And all of a sudden Frank was up there flying among them, mile after airy mile in unison. Who knows how long it lasted before Kathy turned and spoke to him, words he didn’t catch but that startled him back down, into his body? He shook his head, a horse throwing off a fly; he was a practical man, not given to daydreaming. ‘How long till lunch?’ he asked Kathy who asked Tom who wanted to get another hundred miles at least.
