Not worth $175 million. I don't understand the need for "privacy" and that much acreage in the Hamptons. You are literally surrounded by other self-absorbed millionaires and billionaires who could care less about your dealings unless you are some type of drug or mafia type. Then you're the wrong type that shouldn't be in the area. But certain neighborhoods self-select so the need for privacy or security is really silly especially when both you and your neighbors all paid the $550,000 initiation fee to belong to Maidstone.
I can understand having a house in Westchester, Hudson Valley, or Tuxedo Park with that amount of acreage, but in the Hamptons? No. The whole point of "summering" is the community. The "arrivistes" miss the whole point when they throw up hedges or acquire more acreage in the need of "privacy".
