Kunzig;
What you probably saw was the Beacon Sloop Club, just south of the Newburgh/Beacon bridge ( I-84)
I am at Chelsea Yacht Club, which is about 5 miles north of the Newburgh/Beacon on the East shore .
The Beacon Sloop Club was founded by Pete Seeger. Kind of an un-usual "ducks" in that club. Radical environmentalists. They do some good, but at times go too far in my opinion.
