WASHINGTON - Tens of thousands of mourners lined the procession route from Hyannis Port, Massachusetts, to Boston to say farewell to US Senator Edward Kennedy. Kennedy was lying in repose at the John F. Kennedy Presidential Library and Museum in Boston through Friday afternoon, prior to a private evening memorial service. On Saturday, President Barack Obama is to deliver a eulogy at Kennedy's funeral mass in Boston's Mission Hill. Kennedy's body then will be transported for burial in Arlington National Cemetery in Virginia near his brothers, President John F. Kennedy and former U.S. Attorney General and U.S. Sen. Robert F. Kennedy. Kennedy died Tuesday of a brain tumor. He was 77. Union carpenters, immigrants, students, business people, retirees and former campaign volunteers stood along the procession's route to say goodbye to the man who represented Massachusetts for 47 years in the U.S. Senate, The Boston Globe reported Friday.
