Capital of the Commonwealth of Massachusetts and home of the Boston Redsox, Boston was one of the central and major influences of the American Revolution. Often called the 'Cradle of Liberty', several important battles occureed in the Greater Boston area. Often PODs concerning the Revolution at the very least include the city even as a side note.
Having committed sacrilege in British eyes by destroying all that precious tea (oh, and starting some forgettable colonial rebellion), Boston then proceeded to fund IRA terrorism well into the twentieth century. It only redeemed itself by being the setting of Cheers, even though no self-respecting Bostonian ever has, nor will ever set foot in the Cheers bar. Home of the Boston Red Sox, the best baseball team in the history of ever.
