The third annual Riverkeeper Sweep takes place tomorrow.
There are nearly 80 service project sites and 27 of them are in Putnam, Rockland or Westchester counties—including the intriguing "lost beach" in Ossining. See the full list on the Riverkeeper Sweep webpage here.
Riverkeeper says its annual Sweep connects volunteers to dozens of shoreline cleanups, tree-plantings and other service projects. It is the signature New York event in the Waterkeeper Alliance SPLASH Series event, presented nationally by Toyota, and designed to connect people to their waterways. See all their sponsors.
