River Day is a festival-style event with an emphasis on hands-on activities that teach children and adults about the area’s fragile watershed, and how 18th-
century HudsonValley residents performed such marine-related tasks as fishing and boat building.
Van Cortlandt Manor history interpreters will demonstrate 18th-century tasks such as fishnet tying, cooking, milling, coopering, and blacksmithing. Visitors will be encouraged to lend a hand. Sunday, Aug. 13th. For information call 914-271-8981, www.hudsonvalley.org
