Which city is this?
The very first opening shot - with a highway, lots of traffic and, most of all, rolling hills - implies that it's somewhere Southern California.
But the housing, the park and, most of all, the nature of the characters and their attitudes, imply that the location is somewhere in the northeast US, most likely Boston.
