I have lived in NYC, Stamford, and Hartford- and only in Boston do I get that "fight" vibe! Does Boston have a "fight" thing because there are "tribes" from Southie, the North End, Charlestown, and then the Suburbs all coming into Boston in groups of 5 to 10 looking for trouble? Boston is a "fight prone city". I never saw a bar fight in NYC, Stamford, or Hartford. I came back to Boston and saw three in one night.
