It's an amazing book and you may find that it sticks with you for a long time.  I loaned my copy to my son, who works at the same college as the author.  He's talking about getting it signed for me. 

I read that one too.  It was very good and scary to think about.

Right now I am reading survivors by james wesley, rawles- it is about the economy collapsing and I am terrified reading it.  It is so scary what happens and what people sink to.  Makes me want to go out and buy guns, gold, and silver!
