I don't question trying to survive bad scenarios in general but nuclear in particular.

People seem to say a nuke isn't as bad as we think, but the problem is that in case of a nuclear war, there won't be only one nuke, so the amount of radioactivity will be very high and a nuclear winter mean that even if you survive radioactivity nothing will grow for at least 5 years so you'll end up starving.

I could see myself try to take on a "Mad Max" like scenario, not a nuclear one.
