(Remember the 'one if by land, two if by sea' lanterns warning of the direction from which the British were coming?) Most visitors, even those here for just a day or two, fit into their itinerary at least one of the sights they heard about in history class, such as the Old North Church. Sure, it's great to go shopping in historic Faneuil Hall or follow guides in powdered wigs around the Paul Revere House. But Boston is also a cutting-edge city, thanks in part to all those universities and the large student population. Look for clubs hosting the latest indie bands, restaurants with the trendiest fusion cuisine and boutique hotels that are so minimalist there's barely a place to sit down.
Like most places in Boston, Logan Airport is served by the oldest subway system in the US, the MBTA, known locally as the 'T.' There's also a water-ferry connecting the airport to the downtown harbor. If you prefer, a taxi ride to downtown will usually take just 10 minutes. Trains and buses arrive at South Station, which is also on the T. See Amtrak for intercity train information.
Major bus lines Greyhound and Peter Pan also operate from the South Station hub.
