Hence why we're still in the planning stages; it's one thing to throw a bunch of survivors into a scenario, it's another thing to throw them into one where they can stay alive long enough to fight their way out. And to do that they need lasting food and water supplies. If we can be in a huge barricaded building of some sort, (which is a no-brainer in that situation) then we can grow food in planters on the roof or something. Then I'd be satisfied with the living situation.
