You are probably right that a hurricane is the most likely natural disaster. The good thing about hurricanes is that we'll probably have plenty of warning in advance. I wouldn't want to be paddling up the Hudson in a rubber boat though. Nothing like the prospect of 200 mph winds less than 48 hours away to provide plenty of motivation though.

I for one would be very interested in your NYC centric prep ideas. I have a few ideas myself. Who knows, maybe with enough interest even an ETS NYC get together?
