I'm glad this thread got started, and I will be following the discussion with interest.
I had been reading a book on When the silk hits the fan, and I have come to the conclusion that despite my keeping a continuous supply of extra food (a lot of extra canned/bottled, etc.) around, it will not be enough.
I think that things will go south (no offense meant to those actually in the south) in a big way. I don't really believe in the whole 2012 hype, but with the way the world economy, and the mind set of many of the people is, it is going to be very unpleasant, soon. I don't know if it will be in a month, or six, or several years, but I just have this feeling that we are hovering on the edge of the abyss. I live in town, though on the edge of a canyon, and am fervently wishing I lived further out, off a dirt road in the middle of nowhere.
