I think the toughest thing about NYC is that if anything does happen. If we ever get a decent hurricane, there may be a whole lot of people displaced and may be few resources for anyone who remains. If you think about foraging for food or fuel in NYC, there is a very limited supply, relative to other areas.

However that said, show me any place that has people that behaved better than New Yorkers did when things went wrong over the past seven years.
