A shofar blowing in May? How unusual. On Sunday morning, May 26, sunshine sparkled on the rhododendrons, irises, trees, and shrubbery in lovely Jamaica Estates and on the faces of the record crowd lined up at the starting line for the 18th annual L’Chaim 5K Run/Walk for Israel. Assemblyman David Weprin of District 24 counted to three and then Rabbi Shlomo Hochberg, rav of the Young Israel of Jamaica Estates, blew the shofar that sent the runners and walkers down the tree-lined path that wound through Jamaica Estates and trailed through part of Cunningham Park, finishing across the street from the Young Israel. Police stood guard and directed traffic. Most streets were blocked. There were volunteers along the way, encouraging runners and walkers.
