The Gordonville Fire Company Mud Sale is the largest farm equipment sale of its kind on the east coast. It's the largest MUD Sale in the world. Mud sales originated in Lancaster County, PA almost 60 years ago when the Bart Township Fire Company conjured up the idea of having a donation/consignment auction to raise funds for the fire company. Today, dozens of Lancaster County fire companies (and a few outside the county) put on these fund raising sales.
