Shirley, thanks for info, will indeed do a search as you suggest. Also helpful to know you visited recently at the same time of year so may come back with some specifics for planning ideas a little nearer the time if that's OK.
Briar Rose, thanks for the link, great site. Noticing you're from Long Island is actually very topical at the moment. Just this morning finished a book Plum Island by Nelson Demille. Fantastic novel and I've been reading about Long island Sound, the North Fork, Gardiners Island, Shelter Island, Orient Pt. But particularly Plum Island.
Excuse my ignorance and naiivity having never visited or studied that part of US but does this island actually exist or is it purely fictional?
