Okay so I can't really say that I buy into the whole "underground war" thing but some things have led me to at least entertain the idea. A few years ago there were a few very loud, earth shaking booms from deep underground here- deeper than the manmade cave system. Fort Knox (45 minutes away) did not have anything going on at the time and swore it wasn't them (center of boom was not very close to them anyway) and scientists swore there was no earthquake activity (New Madrid expanding north?). Mammoth Cave system is about 1 1/2 hours south but it is the "tourist" end of the system and the boom seemed to be centered just south of Louisville. No explanation was ever determined, no explosions known of. Very curious!
As an American it's your responsibility to have your own strategic duck stockpile. You can't expect the government to do it for you.
