I mean this question in all seriousness (as it not trying to flame here) but what's the deal with the yuppies? Who are we talking about here? I don't know if I have my blinders on or perhaps just an outdated view of who/what yuppies are but I used to work in Manhattan (commuting in from Brooklyn before it was the "hep" place to live) and I saw yuppies there, plenty of them (around where I worked, not where I lived, obviously). And I'm can't say as I've seen much of these types of folks around here but I'm either not seeing what's right in front of me or that yuppies look/act differently around here or that what is considered a yuppie around Boston is different from NYC. We're not talking about college undergrads here, right?
