Boston a great town this time of year. The Patriots with the wins are going to be in foxboro this weekend and the Red Sox and Yankees will be midstride.
Other than sports, i would say Fanuiel Hall, Cheers Bar for a drink, Freedom Trail, Cambridge if you are interested in seeing Harvard and MIT, Charlestown has some great history with the shipyard and such, and the North End has some great restaurants, and walking down the Charles River can be relaxing.
Enjoy and leave your yankees hat at home.
