An ongoing art show and lecture series on Plum Island at the Old Lyme Phoebe Griffin Noyes Library and St. Ann’s Church is one of several initiatives being used to let people know about the island, and how they can help save it from development.

People who want to help can become informed, write to the legislators, write letters, and tell their friends and neighbors about the initiative, says Chris Cryder from Save the Sound.

To get specific suggestions for how to help, visit preserveplumisland.org and go to “How You Can Help,” and sign up for e-mail alerts through the link at the top of the home page.

The art show, the brainchild of painter John Sargent featuring both his work and that of photographer Robert Lorenz, is at the Old Lyme Phoebe Griffin Noyes Library (OLPGN) 2 Library Lane, Old Lyme, and at St. Ann’s Church, 82 Shore Road, Old Lyme.
