My imagination got the best of me when I read the headline. I pictured an isolated civilization run by babies. Baby shopkeepers, baby baristas, baby firemen, and baby butlers.
But no. It turns out to be much less hilarious than that. The island in question is called Hoffman Island, a manmade piece of land located just off Staten Island. 100 years ago it was used as quarantine for sick children who came into Ellis Island as immigrants.
During World War II it was used as a marine training center, and after the war plans were considered to turn the island into a park. That never happened.
Today the buildings are long gone, and Hoffman Island is off limits in order to protect wildlife. But a few years ago a local triathlete swam the mile to the island with some friends who joined him in kayaks. He gives a full account on his blog, and links to a gallery of photos they took.
