The increased inflation rate in the 1960s, the US monetary devaluation, the continued concern over a possible nuclear exchange between the US and the Soviet Union, and perceived increasing vulnerability of urban centers to supply shortages and other systems failures caused a number of primarily conservative and libertarian thinkers to promote individual preparations. Harry Browne began offering seminars on how to survive a monetary collapse in 1967, with Don Stephens (an architect) providing input on how to build and equip a remote survival retreat. He gave a copy of his original Retreater's Bibliography to each seminar participant.[citation needed]
"So you know, I'm not a survivalist nor am I really very outdoorsy in general. I'm basically a relative novice prepper, but what I was looking for with this book was more like "have a plan after the plan" resource. I got to thinking that survival would be necessary after an emergency, but at some point, it would need to become how to live your life with whatever changes there had been in the world. So this was more like an "ok, I survived, what do I do now?" pick for me."
It’s impossible to carry all the food you will need for a week unless you’re eating very high density proteins like nuts.  Nuts and dried meat are two of the easiest off-the-cuff meals.  Canned food has a lot of water that is wasted during the cooking process.  Stay away from heavily flavored or salted nuts.  The amount of salt present in the unsalted nut mixes is still sufficient enough to replace electrolytes.
