Somerville
City that's only about 10 minutes from Boston. Depending on the time of year, a little warmer/colder than Boston. An ethnically diverse city with people from every continent (but Antarctica). Haven to university students (close proximity to Lesley, Tufts, Harvard, etc.) and immigrants to escape high rent costs found in the neighboring cities of Cambridge, Arlington and Boston. Not a big city, however; 15th most densely-populated inc. place in America (greater pop. density than San Francisco).
Man 1: Hey, buddy, so I just learned where the first American flag was raised on January 1, 1776.
Man 2: Really? That's cool, where?
Man 1: On Prospect Hill, in Somerville, Massachusetts.
