The Board of Selectmen on July 27 held a dedication ceremony for the Massachusetts chapter of Rolling Thunder Inc. The national advocacy group is a nonprofit organization with 90 chapters across the country. The organization strives to publicize issues involving prisoners of war and those missing in action, spending $500,000 each year to increase awareness about the POW/MIA issue and other injustices suffered by veterans. Incorporated in 1995, the group’s motto is “We will not forget.” During the Stoneham ceremony, an empty chair was to be installed at Town Hall in honor of the 91,000 American soldiers who remain unaccounted for. “This is their chair until they get home,” said Joe D’Entremont, president of Rolling Thunder’s Massachusetts chapter. He said he hopes town officials will bring the chair to local public schools to educate students about the POW/MIA issue. “Our mission right now is to get all 351 cities and towns in Massachusetts to hold these dedication ceremonies,” said D’Entremont, noting that a similar chair has been installed at Gillette Stadium and in neighboring Wakefield. “The effort is in its infancy right now,” he said. “It’s a huge undertaking.” For more information, e-mail email@example.com.
