Greater Boston—a metropolitan center and one of the oldest and most historically significant areas in the United States—features an eclectic mix of old and new, from historic attractions, such as the Freedom Trail, the USS Constitution and Boston National Historical Park, to cutting edge restaurants and nightclubs. Located across the river from downtown Boston, Cambridge is home to Harvard University and the Massachusetts Institute of Technology (MIT), two icons in American post-secondary education. John F. Kennedy, one of the most influential presidents in the history of the United States, was born in nearby Brookline. His boyhood home is preserved as the John F. Kennedy National Historic Site, with rangers offering guided tours. From September through December the New England Patriots play football in the NFL at Gillette Stadium in Foxborough, from October through April both the Boston Bruins play NHL hockey and the Boston Celtics play NBA Basketball at the TD Banknorth Garden, while March through September sees the Boston Red Sox play Major League Baseball at historic Fenway Park. Other cities to visit while in the Greater Boston area include Newton, Quincy, Waltham and Brockton.
