I took this picture today. I am told that today's farmers have computerized controls that will hold the tractor in a straight line, but I am still amazed at how they can plow straight for as far as one can see.
When I married into Linda's family, her father used to allow me to drive his tractor. I was a jet pilot in the USAF at the time. I thought that anyone who can fly a jet airplance can certainly drive a tractor. I learned that it takes more concentration to plow a straight furrow than it does to land a plane.
