Agreed. I've often felt that an inflatable / collapsable boat of some sort would be a good last-ditch effort tool to get out of the city and up to my in-laws place in the Catskills. Roll it down the hill to the Gowanus and start paddling. . .

I've come to the conclusion, however, that the most likely widespread natural disaster in NYC is a hurricane direct hit, and I would not want to be on the water if that was the case! Thus, most of my preps involve being ready to bug-in for a few weeks. Hence, my concerns about the water system.

I have plans for a more detailed post on urban/NYC centric preps. It seems like there's some interest, so I'll try and get to work on it.
