I feel qualified to pass judgement on the advice in this book, and I recommend it to all readers without hesitation.
It is fashionable to dismiss "preppers" as a bit too far out there: digging bomb shelters, armed to the teeth, eating snakes and rats. But the truth is, as is proved to us again-and-again and with alarming frequency, it's important to be able to be self-sufficient for at least a few days or weeks.
In the West we live a highly technological life, a just-in-time life, a co-dependent life. For the most part our systems are robust in daily operations but, when one takes the time to pull back the curtain of civilization, our systems are also extremely fragile.
The recent Russian Meteor could have been over your family. Hurricane Sandy "surprised" a lot of New Yorkers who'd become complacent. The record snows last week in New England are becoming more severe. Drought, Fires, Tsunamis, Solar Flares & Coronal Ejections (which can take out satellites, disrupting both electrical grids and telecommunications.) The list of probable inconveniences is endless. The list of possible disasters is lengthy.
Not only have I been on the fringes of the survivalist/prepper movement since the 70's, but I have also also spent time as a soldier, a decade as a cop, and 20 years as cruising small sailboats (our self-contained answer to "getting out of the way" if civilization collapses. Think of it as an escape capsule in paradise ;-> )
We have also spent the last 25 years as a Navy family, much of it on Guam, where we weathered 5 major typhoons in one year (including Omar & Yuri, both Super Typhoons) and earthquakes (an 8.1 in 1993 that wrecked island services --water, gas, electricity, telephone-- for six weeks. While on Guam we also housed, clothed, fed, and transported survivors as personnel were evacuated from the Philippines after the Mt. Penatubo volcanic eruption.
On a smaller scale, we survived Guam's chronic power shortages --enduring rolling electrical outages that left our area of the island without power for 3 hours per day, usually about dinner time-- by having our propane camp stove on the kitchen counter. We also became quite good at cooking pizza on the Weber charcoal grill.
To the book in hand, what I appreciate most about Bradley's writing is it's evenhandedness. Unlike many survivalists, Bradley emphasizes self-sufficiency first, but also community building. He's pro-gun, yes, but not just in the service of self-protection but also protecting your community. In Bradley's book guns are a tool, like shovel or an axe. Readers will find that no specters of mowing down hoards of the starving from your lonely mountain redoubt haunt this book, for which I am thankful.
Bradley's message is this: If you cannot help yourself, you are in no position to help others either. Your friends, your neighbors, your neighborhood, survive after a disaster.
BTW: I am an avid ebook reader. But in the case of a long-term disaster (an ElectroMagnetic Pulse attack or certain solar disruptions that may affect electrical power and communications), it's advisable to have all reference books in hardback. Medical, first-aid, vegetable gardening, auto repair, etc. This belongs book belongs in your hardback reference library.
