A pack of surfers are braving New York’s waterways today, circumnavigating the island of Manhattan, to raise money and awareness for autism charities. The surfers, taking part in Sea Paddle NYC, started paddling north from South Street seaport at 9 AM. We caught the group minutes later paddling by one of Olafur Eliasson’s waterfalls. For a closer look, check out live photos of the surfers’ 28 mile journey, which finishes up in Battery Park City this afternoon.
