Here are a couple of pics of an oil well in Noble County, Oklahoma.  The prairie stretches for miles with little change in elevation.  This well sits on a small hill and hasn’t operated for months, maybe years.  Suffering from time, rust and neglect, the jilted little pumping unit sits, waiting in vain for its long disillusioned owner to return and impart a little TLC.
