What to do in Cambridge, MA

Big, Excellent, Varied art museum. Beware the layout: just when you think you have seen it all, you will stumble upon a gallery that you haven't seen yet. (2 hours minimum but you could easily spend much more time here)

A huge museum building that includes a Geological Museum and the Peabody Museum of Ethnology and Archeology (not to be confused with the Peabody Essex Museum in Salem). Don't miss the Kronosaurus. I recommend 2.5 hours minimum and you could spend much more time there.

This foot bridge over the Charles River straight up from Harvard University offers an excellent view of the Charles with the Harvard Business School on the far side of the river and the other Harvard University behind you. Sit on a bench and watch the people and the Canadian Geese. If you come during the October weekend of The Regatta, you can watch the various rowing competitions.

This independent movie theater on Brattle Street is still going strong. Movie selections often only play for that day so check the website to see what is playing when you are in town.

Interesting museum with a scientific bent, including exhibits on holography and cutting edge computer uses.

A quirky and beautiful concert venue, with good acoustics too.

Rent a canoe or kayak to paddle on the Charles River. Two locations.

Best Chinese restaurant in Cambridge; they make their own dumplings.

There is a variety: the American Repertory Theater Company at the Loeb Theater and the Oberon Theater, the Harvard University Theatre Society at the Loeb, companies in residence at the Central Square Theatre and a variety of local theater groups playing at places like the YMCA in Central Square or the Dante Alighieri Italian Cultural Center near Kendall Square.

Take a guided tour of Mr. Longfellow's home, a National Park Service site.

We have a few left. As they are so spread apart now, here is a current listing. In Central Square: Rodney's Bookstore, Pandemonium Books and Games, Center for Marxist Education, and Seven Stars; in Harvard Square: the Harvard Coop Bookstore, the Harvard Bookstore, The Raven, and Grolier Poetry Book Shop; in Kendall Square, the MIT Coop; and in Porter Square, Porter Square Books.

Excellent ice cream made on the premises; located between Central and Kendall Square.

a green park next to Harvard Square--- Here you can walk around THE tree under which George Washington stood when he first took command of the colonial militia in the Revolutionary War. You can find that tree over by the cannons. The Common also has a playground on the far side and lots of open space. (Perhaps you will find room to sit with a slice of pizza from one of those overcrowded pizza spots in the Square.)

A cemetery in a garden setting with some impressive grave stones. This cemetery covers over 100 acres. It is a lovely place for a walk if you want to get away from the urban scene. Wikipedia's description includes the phrase, "classical monuments set in a rolling landscaped terrain..."
