Also, for those not from the area, JP is indeed a "Boston neighborhood" but it's on the outskirts around parkland, the Arnold Arboretum, etc. and is about a 30 minute public transit ride [edit: on the Orange line not Green line]. So don't imagine this is in Boston in the way many might imagine. It probably has more in common with close in suburbs like Arlington than downtown.

Of course, the reason that Arlington doesn't have better transit links is that they didn't want it when the Red line was extended to Alewife. JP is certainly less suburban than Arlington but it also doesn't (to me) really feel like it's in "the city."

If I go into Cambridge after work, it takes me something like 45 minutes to get to Alewife near the Arlington line in pretty nominal reverse commute traffic. It takes me a good other half hour to go the last few miles. (And that's Cambridge. Boston would take even longer although I'd normally take a different route from my house)
