George Washington’s farm marks the beginning of the wheat harvest season July 4 with wheat-treading demonstrations at the George Washington: Pioneer Farmer site. Costumed staff will lead Mount Vernon’s horses as they tread wheat in the 16-sided barn at 10:30 a.m., 11:00 a.m., 1:00 p.m., and 3:00 p.m. every day. Visitors can witness Washington’s innovative treading process, learning first-hand how Washington separated grain from straw.
