Crop Circles

I always find it interesting the things you see and how differently places look when flying. I particularly find that flying to the west always has interesting features like mountains, canyons, weird desert formations, and man made items. One in particular are the crop circle that you see dotting the western par of the great plains in the southwestern states. They make unique pattern across the landscape of pretty barren areas. If you have not seen these or how they are created, they are irrigated farm land which the irrigation device operates in a circular direction receiving water from a pivot/hookup point in the center of the circle.
