Mayor Bloomberg and a group of school children heralded the start of the city's outdoor pool season by jumping into the Jackie Robinson Recreational Pool. Besides paying tribute to Michael Jackson, Bloomberg said, "By mayoral order, I am for now declaring school's out, pool's in." (The music? "Don't Stop 'Till You Get Enough.") WCBS 880 spoke to 9-year-old Celia Rodriguez about the mayor's swimming techniques; she was surprised he was a good swimmer, "Yes. He can float on top." Keeping with his tradition, the mayor kept a t-shirt on while in the pool. For more details on the city's outdoor pools, here's information from the Parks Department. Photo: WCBS880
