I'd worry about any population center. What annoys me to no end are the NY'ers (Mind you I live and own a home in NYC) who bellyache and have no sense of proportion on how vital it is for us to win this war, the rest of the world opinion be d*mned.
For myself, I'd like move to New Hampshire if I could get my wife on board with the idea. Houston seems nice (never been there though) but the property taxes look outrageous.
