Mine is good foodwise for about 72 hours, and less with water. I'm not really even good for two days on water. If I was trying to leave NYC, getting out of it while carrying enough water for three days, and nothing else, would be difficult, unless driving is a real option. If I can do that, at least another 5 gallons comes with me. The limit on carrying food has made me think about adding stuff to my BOB that could allow me to get more food; snares, fishing kit, etc.

If I Bug-In, the supplies will last longer.
