Wrapped in a tube-and-fabric Piper Super Cub, window and door open, flying low and slow over the countryside is an incredibly intimate way to explore the United States by air from the Appalachian Mountains across the Great Plains to the Rocky Mountains. Cars pass by on interstates (literally, sometimes they pass the Super Cub), trains meander around mountains, farmers spray their crops, boaters enjoy a warm day on a lake, deer run free on plateaus, and cattle graze on ranches—all going about their business seemingly unaware of their observers in the air.
