Flynn’s Fire Island played host to a gathering of people at Ocean Bay Park who had one thing in mind: saving the Great South Bay.

That, and having a good time.

The fundraiser for the Save the Great South Bay nonprofit advocacy group featured free beer and prizes from Blue Point Brewing Company, which included a paddleboard, and Blue Island oysters.

The event also included discussions about the health of the bay, led by Save the Great South Bay co-founder Marshall Brown and Enrico Nardone, the executive director of the Seatuck Environmental Association.

The organizers also screened some of the 4-minute videos from The Nature Conservancy on Long Island’s special series on nitrogen pollution that was released last month.
