Query: this guys nuts

im a survivalist and so i was excited about the book....until i read it. for 90% of the population, this is not for you. the outhor writes as if EVERYONE is watching you. he focuses mostle on how to avoid people from finding your cashe and throwing off metal detectors of "those people" who are trying to find your stash (as if those people are watching you already). its useless as for storing/preserving food, but covers how to store non perrishable items. but like i said, if youve seen Mel Gibson in "conspiracy theory," then you can relate to the outhor of this book. i wish i didnt buy it. this is for an extremest who has slightly lost touch with reality.
