I see no reason not to read the survival guide, it brings up plenty of good points, though I wouldn't trust some things in it. It got me thinking in ways I wasn't before I read it, which made it a good read for me.
i can argue with a lot of things from that book, but even I have used a few pointers....
"Day by Day Armageddon" and the sequel, "Beyond Exile". It's a journal of a Navy pilot that goes AWOL during a zed outbreak. I liked them both so much I've read them multiple times.
