Things that make you go "hmmm..."

So no doubt you've heard about the massive power outages in the northeastern U.S. and Canada. (look here or here for info) Frankly, I'd be surprised if you had heard about anything else, that was all that was on the news yesterday. It was on all the local networks here, plus the cable networks, as well as the BBC news. My question is this. If there was no power in NYC yesterday, how on earth was NBC broadcasting from NY at all? Or any of the news agencies that are headquarterd in NY. Is it all a lie? Are they really just in a small building in Sheboygan?
