Harvard is in Cambridge, not Boston. But try telling that to Grandpa bob back in Cuddlefish Creek, Mississippi.

You can't. Never mind the fact that Cambridge is equipped with its own historical landmarks, theaters and neighborhoods. An anthology of tales about eight-hour organic chemistry labs, lunches in the Pit with preteen punks and idle afternoons lingering over coffee and croissants at Au Bon Pain does not a complete Harvard Summer School Extension student make.

There's no excuse for leaving Harvard without ever setting foot in one of the oldest and most fascinating metropolises in America. Fleeting images of skyscrapers, the townhouses of Back Bay and the Boston side of the Charles River on your cab ride from Logan Airport simply won't do.

On your first trip into Boston, don't be afraid to play tourist. The first thing tourists hit--especially those who are also history buffs--is the Freedom Trail.

The trail, a red line painted sidewalks or laid in brick throughout the city, will lead you on a three-to four-hour tour of the city's most prominent historical landmarks as well as Boston's traditional Italian neighborhood, the North End.

You can reach the trail by rail. The Boston subway system, par of Massachusetts Bay Transit Authority (MBTA) and called the T, is the oldest in the nation. And its four lines (red, green, blue and orange) will take you everywhere you need to go for just 85 cents a ride.

From Harvard Square, take the Red line inbound and get off at Park Street. There you will find Boston Common, a 48-acre green oasis of fountains, monuments, relaxed Bostonians and other tourists. Bought by the city in 1634 as pasture land for cows, goats and sheep--and later used as a military training ground--the Common is the oldest public park in the nation.

At the Boston Common Visitor Kiosk ask for a guide to the Freedom Trail and let the red line (not to be confused with the subway line) take care of the rest. Along the trail, must sees for history buffs include: the State House; the Granary Burying Ground, final resting place of not only Samuel Adams and John Hancock but also of your childhood friend, Mother Goose; Old North Church, of Longfellow fame.

Perhaps the most lively and frequently visited spot along the trail is Faneuil Hall marketplace, where you'll find jugglers, magicians and street musicians entertaining crowds in front of a variety of restaurants and shops.

Enter the pillared Quincy Market building and your nose will be assaulted by a million appetizing odors--fresh lobster, pot pies, egg rolls, empanadas, pizza, fudge brownies and more. The food court houses more than 20 stalls from which even the most finicky tourist can chose a tasty meals.

The Market was named for Josiah Quincy, the mayor who in 1823 designated the site for the public sale of produce and fruit.

In the mood for a little shopping? Flanking Quincy Market are pricey gift and craft shops as well as such traditional favorites as Victoria's Secret, The Sharper Image, Banana Republic and The Gap. Don't forget to visit the seven-story Limited.

If you're a theater fan on a tight budget, stop by the Bostix kiosk, where you can get half-price tickets to may plays at Boston area theaters on the day of the performance.

Faneuil Hall Marketplace is easily accessible by T as well. Take the T to Government center on the Green Line and walk past one of the few architectural monstrosities in Boston--the anti-organic upside down concrete City Hall--to this festive shopping and eating complex.

Back on the Freedom Trail, you'll move on to Haymarket, Boston's open air produce and fish market. There vendors sell their in-season fruits and vegetables at wonderfully low prices.
