Anyone who has watched the movie "Southie", note that it's really, really inaccurate.
Southie is a mostly Irish working-class neighborhood. But just because it's "blue collar" doesn't mean it's unsafe or run by gangs. On the contrary, it's one of the safer areas in Boston.
And the shore is really nice.
Yuppie #2: Up and coming is tentative, it's still a fairly rough neighborhood
