    "Mount Sinai offers a small school district with one of the highest ratings around...almost a private school system with small classroom size and much attention for the kids. Living in Mount Sinai offers plentiful shopping, beaches, marinas,close proximity to public transportation, ferries to Connecticut, and nearby the botique village of Port Jefferson. This home backs to a wooded buffer and offers privacy, solace, and nature. Nearby Cedar Beach offers pristine sand and surf from the Long Island Sound...the Mount Sinai Yacht Club offers affordable mooring for your boat and a community of people enjoying life to the fullest...there is the "Wedge" which offers a walking trail, playground for the children, a community center offering seasonal activities, and community members which really care for each another...Mount Sinai offers a history dating back to colonial times with some historical homes on the National Register...a New England atmosphere welcomes guests and makes a person want to call it Home."
