From years of watching Gilligan's Island, I knew that quicksand (which frightened me) was common on islands. When I learned that Manhattan was an island, I was terrified by the thought of an upcoming trip there. I comforted myself by planning to stay only on pavement or in buildings AT ALL TIMES, fortunately pretty easy in Manhattan. I survived.
