    "The most glorious thing about Babylon Village is that nightlife, shops, parks, marina and pool are all within walking distance...unless you want to visit the ocean beaches. It’s a village where neighbor looks out for neighbor. The school looks like a college campus overlooking Argyle Lake. The historical society, beautification society and the mayor’s office keep Babylon’s history and traditions alive. Great place to live!"
