A Million Ways To Celebrate In Boston

The Boston Celtics are celebrating their historic NBA championship Friday.

Players boarded the city's famous duck boats as throngs of fans lined the streets for the rolling rally.

Some die-hards started arriving at least four hours before the parade's start time.

City officials expected more than a million people to show up for the celebration.

There have been no reported issues.

The Celtics defeated the Dallas Mavericks four-games-to-one to earn their 18th title, the most ever by a NBA team.
