Diana Nyad, the 64-year-old Native New Yorker who swam from Cuba to Florida without a shark cage is attempting to swim in a pool set up in midtown Manhattan for 48 straight hours to benefit victims of Superstorm Sandy. Yesterday, she dove into the 40-yard pool set up in Herald Square in front of Macy's and began doing laps shortly before 9 AM. Her goal is to raise money for people still struggling a year after Sandy. Last month, she became the first person to have swum from Havana to Key West, Florida without a shark cage. Contributions are being accepted by the disaster relief agency AmeriCares Foundation, which will distribute the funds to the victims of Hurricane Sandy.
