Outdoor Event Venues Maryland - Over the past 65 years Circle D Farm has continued to evolve and improve our facilities. We always try and keep up with the times as they change but keep true to our history as a working farm. We are a family run operation and we all have the privilege of being able to live on the property. Because of this we constantly strive to maintain and upgrade the farm. Small things that go unnoticed at commercial facilities or larger operations are quickly addressed at Circle D Farm.
