    "Polar opposite experiences from when you enter downtown Riverhead, which is not to be considered as safe as communities closer to the other side of town ... where many neighborhoods and developments are located up and down Sound Avenue ... and just blocks from a handful of public and private beaches overlooking the beautiful Long Island Sound.
