i'll be going to port jefferson and mt. sinai this weekend and wanted to get some advice about the area. does anyone know anything about mount misery cove? i have see quite a few moorings in there in winter time. can those be used? is there a fee? how is the swimming in the cove (being that it is "spoil area"). or is the old field beach a better choice? also, any advice on spending the night in mt. sinai harbor vs. port jefferson? thanks!
