(Let's be honest here : I find building a shack in your backyard to stockpile beans in case of total collapse f.... stupid
It goes without saying that a modicum of preparation for disaster can be helpful-I have several cases of bottled water and canned food with flashlights in case of a lenghty power interruption (that fairly minuscule amount of preppyness is based on a realist outlook of a global disaster in Montréal)
But the kind of people they show on Discovery Channel or the like....In addition that a lot of them follow utterly insane stuff (supervolcano ! polar inversion ! nuclear attack on the US ! SRA global plague, FEMA stormtroopers), the ones that have comparatively normal fears (US currency collapse, another democrat in the white house), why exactly they are stockpiling ? (Especially, as those are proud Americans, ammo and guns-very useful in nuclear winter (1))
If Niburu smash the Earth, do you think that having six months of can of beans will change much ?
(1) Yes, I know, shoot looters coming to steal your cans of dog food. In addition of having to guard 24 hours on 24 your dilapidated house deep inside Montana for the rest of your life, I would say that some people are hellbent on the Falllout IV raider lifestyle)
