The Beacon Film Society presents a special screening of the film "Down by the Riverside," which tells the story of folk music icon and Hudson Valley resident Pete Seeger and his boat, the Hudson River sloop Clearwater, and the environmental movement it helped launch in the 1960s. The film will be followed by a Q&A with co-directors Jodie Childers and Dan Messina. CLICK HERE to purchase tickets for the screening at the Howland Cultural Center. ..
