What does it take to make a very big splash on Boston Harbor? "It takes clean water, live lobsters for the touch tank, 1,200 hot dogs and buns, 1,800 bottles of water, 10 boxes of fresh fruit, carrot sticks and cheese, dozens of volunteers, 12 lifeguards - and 744 kids," said Bruce Berman of Save the Harbor / Save the Bay, which hosted its 3rd Annual Kids Beach Bash and Splash on Thursday August 15th at the Boston Centers for Youth and Families Curley Recreation Center at M Street Beach in South Boston. Youth and teens from 15 youth groups from 11 communities, including South Boston, Braintree, Chinatown, East Boston, Everett, Dorchester, Fenway, Haverhill, Jamaica Plain, Roxbury and the South End took part in the celebration. The party included traditional beach activities such as kite flying, fishing, face painting, sand castles, touch tanks and Frisbee. It also included a performance of the classic sea chantey “Haul Away Joe”, led by Save the Harbor’s maritime historian David Coffin and the official Save the Harbor rap led by Save the Harbor lead Boston Harbor explorer Will Clark. It was a “Sea of Smiles” on the beach at noon, when more than 500 kids jumped in the water under the watchful eyes of lifeguards from the Boston Centers for Youth and Families, the Department of Conservation and Recreation and the Greater Boston YMCAs. So far this year Save the Harbor / Save the Bay's free summer youth programs have brought more than 6,000 youth and teens from area community organizations and youth groups on free day trips to the Boston Harbor Islands.
