many of the campgrounds in that list are across the sound in Connecticut, a few of those we have camped at. Our daughter went to college in Southampton, Long Island, so we made many trips out there. Driving out on the Long Island Expressway could be an experience. We mostly would get the ferry out of New London CT to Orient Point LI to avoid going near New York City. Daughter now lives in New London. My Trailer Life campground directory only shows 4 campgrounds on Long Island. We did check out one, I think it was the one out by Montauk. Just a flat, open area. Campsites in rows, as I recall.
