The Riverkeeper Sweep 3rd annual day of service for the Hudson River estuary will be in the Hudson Valley and New York City on Saturday, May 10, and they are counting on us to make it a success. Last year over 1,400 volunteers descended on 72 locations along the Hudson River and its tributaries, removing over 38 tons of debris from our shores, and planting 300 trees.
