there was a discussion about this phenomenon, which got quite heated if i recall, elsewhere. i was suggesting that lots and lots of cities, unlike new york, have 'burbs that are often times considered "the city." to use an example i've used, i had family who lived about 30 minutes outside of downtown chicago, if not the city limits, but if you asked them, they were from "chicago." this seems apply to what we're seeing here as well. note, this would never happen in NYC, ostensibly due to the rigid and distinct geographic borders which with is as has been blessed.
