The Witchita Hills area in Oklahoma. Nothing extraordinary, it was just a beautiful, quiet place that took me back a hundred years. Nobody around, buffalo and longhorns wandering all over the place, and some nice little fishing lakes. Not real unique, but an adventure. But unique wise- nothing in the world was more impressive to me than coming around the corner and seeing Lake Powell for the first time. And even more impressive from a plane.
