The Best 10 Beaches for 2017 in Southampton, NY, United States - Yelp -
I think at least that #3, #4 are mislabeled?
3. Southampton Village Cooper’s Beach (Dune Rd)
4. Road D (Road D)
I think Cooper's Beach and Southampton avillage Coopers are the same place. Road D Beach is mislabeled on the map. It's an Ocean Beach off Meadow Lane.
