Volunteers are crossing state lines to help clean up neighborhoods that took a beating from Hurricane Sandy. At a firefighter’s home on Beach 135th Street and Cronston Avenue in Belle Harbor, volunteers from the “Church of Jesus Christ of Latter Day Saints” are helping to gut the severely damaged residence, pulling up waterlogged floor boards and hauling out debris. “We’re sorry that we have to be out here, that this disaster occurred, but we’re glad to help people that have the need,” said one volunteer. “It’s really easy for us to come down and give back to guys that are serving all the time,” said another. The church says thousands of volunteers from congregations around the country are helping in the relief effort. Crews from New Jersey went to work Saturday cleaning up the Brooklyn Behavioral Health and Community Rehab Center in Coney Island. They say they’re more than willing to do their part.
