I'm always amazed when I'm reminded of how much certain neighborhoods (okay, i guess they're their own town, but they're part of the very immediate Boston Metro Area) are not looked upon kindly by their neighbors. Namely, Alston and Roxbury. I know definitively of two schools that go to great lengths to ensure that they have only Boston, not Roxbury addresses. Same goes for Alston.
But it seems that Brookline has taken this a step further. This isn't an academic institution not wanting to be associated with a slightly notorious area, it's a neighboring town. So far, I've found that only pretty predominant roads go from Alston to Brookline and vice versa. What happens on the smaller roads? Either there's a barrier at the town line so cars can't pass, or the road stops and becomes a dead end just before the line.
Now, I've never hidden the fact that Alston isn't my favorite place. (also not my most disliked. besides, it has some pretty awesome people) But I think that barriers and prematurely stopped streets is a little drastic. Oh Brookline.
