If one day just doesn't sound like enough time to celebrate Independence Day, you should check out Boston Harborfest, an annual six-day Fourth of July festival that honors Boston's colonial and maritime heritage. Harborfest attracts more than two million people each year and features more than 200 daily events, including concerts, cruises, historical tours, reenactments, and more—many of them free.

The 27th annual Boston Harborfest will take place from Tuesday, July 1 to Sunday, July 6, 2008. Read more.
