Uh yeah, no, if you're staying in the Back Bay and then the harbor (not quite sure what that means but I'm assuming somewhere equally upscale and centrally located, near the harbor) I highly doubt you'd be travelling to or through any of the suspected neighborhoods. They're not tourist areas and Boston is pretty huge. Also if you did, you'd realize what I mean about so many places looking exactly as BigMoaner described. Sorry Hope you have a great trip though! You're lucky that we're having an exceptionally warm winter. This time of year we're usually still covered in snow and freezing.
