2016 Annual Riverkeeper Sweep – May 7 May 4, 2016May 9, 2016wordpress Leave a comment John us in Tivoli for the 5th Annual Riverkeeper Sweep on May 7. It’s lots of fun. We haul a ton of stuff out each year: Tires, plastic, styrofoam. Folks on land and in canoes and kayaks in Tivoli Bays. This is last year’s heap.
