Pretty good account of a spelunking expedition into what was formerly a pretty spectacular civil defense shelter built in the 1960's in New Orleans.
Makes you feel sorry for America that such places are merely curiosities on the eve of World War Three. The 'Kwans are to be pitied.
Here is an interesting blog on the history of civil defense in North Carolina.
Fascinating exploration of a Mojave Gypsum Mine once used for civil defense.
Pay attention and marvel at all the ancient relics they find in these places that were once produced by American manufacturing. This was a constitutional republic that was entirely self-sufficient in the year (1963) I was born. They shot John Kennedy and surprise, forty years later the entire nation is just a dried-out dead husk of a country which has been siphoned dry of every single penny and left with debts so crippling they will never be paid. Kennedy was in the way and he served as an example to every President that came after him. Beware the men who would kill your king. Things do not get better afterwards when they go free. These ancient ruins testify to better times.
Most of these ruins exist because of the strong drive by President Kennedy to introduce a substantial, nationwide civil defense program. After they killed him, that was one of the first initiatives they terminated. Those would have been pennies not paid to them.
