On the southern coast of Vieques lies one of the world's most amazing natural experiences that is likened to legal LSD - the bio bay. Best experienced at night without a moon, you kayak into Mosquito Bay (the body plentifully lubricated with eucalyptus and baby oil) and swim in the luminencent waters, energizing the photo sensitive particles with every slight movement, creating milky swirls and trails as your body is in motion. The blue-green light is produced by trillions of micro-organisms - over 750,000 tiny dinoflagellates plankton per gallon of water...
