Freedom Farm’s daylong polo event brought the sport of kings to BlackBerg Ranch in Watertown. There was a polo match, a best hat contest, tractor and pony rides and a petting zoo. From white tents set up on the sidelines, guests enjoyed hors d’oeuvres, cocktails and front-row seats to the equine action. Funds raised at the event benefit Freedom Farm, which offers therapeutic horse riding to children and adults with disabilities to help improve their mobility, build confidence and encourage personal growth.
