Most people have no ideal how prepared the government was in the 60's and 70's. Many building had fallout areas set up, and in Louisville Ky they had an stocked underground area for 50,000 people. There probably was a lot more cities with the same thing.
So you descend down the rusty ladder of a nuclear fallout shelter built by a nuclear engineer to survive a thermonuclear exchange.
And you find: water - check; clothing - check; medicine - check; TIN FOIL - oh heck yes now we are talking...!
See, no one on this forum needs to worry anymore - if this guy felt like tin foil should be in his fallout shelter, then the rest of the world does not understand - TIN FOIL is what you want in post-apocalyptic situations.
