Mourners lined the streets as a motorcade carrying the late Sen. Edward Kennedy's casket and countless members of the Kennedy family traveled to Boston from his home in Hyannis Port.
Some motorists hoping to catch a glimpse of casket stopped their cars on overpasses.
"I can remember where I was when President Kennedy died, and I'll remember where I was when the senator left Hyannis Port," said 54-year-old Virginia Cain, who walked two miles from her home in Centerville to witness history.
Earlier in the day, a private mass was held at the Kennedy compound in Hyannis Port. Sen. John Kerry, D-Mass., who is the only senator representing Massachusetts for now, also attended the private service.
"The greatest thing was the way he loved serving, and the passion with which he devoted himself to public service even as he was able to devote himself so entirely to his family," Kerry said.
"He loved people, he loved the give and take of politics," Kerry said. "He had respect for everybody. And despite all the things that were thrown at him, he always talked about the humanity and morality and the things that were important to people. And that's a good lesson for a lot of people in politics today."
Kennedy's funeral will be held Saturday in Boston. All of the living former presidents will be there. President Barack Obama will deliver the eulogy.
Kennedy's first stop before his final resting place will be at the John F. Kennedy Presidential Library, where a public viewing be held through Friday. Kennedy will then be laid to rest near his brothers at Arlington National Cemetery.
