Previously i make a few comments on Geoff Clovers post, about the book one second after.
The book made me think a lot about how things could go if the crap really hit the fan.
I guess one of the key things i got from the book is how much better things could go if there was good local leader ship with plans for the what ifs.
Also the locals need to know there are plans for a rainy day.
If people did not panic and was willing to help one another, that would greatly increase your likelihood of survival in a very bad situation
