Followers of James Wesley Rawles[45] often prepare for multiple scenarios with fortified and well-equipped rural survival retreats.[46] This group anticipates a near-term crisis and seek to be well-armed as well as ready to dispense charity in the event of a disaster.[43] Most take a "deep larder" approach and store food to last years, and a central tenet is geographic seclusion in the northern US intermountain region.[47] They emphasize practical self-sufficiency and homesteading skills.[47]
I’ve seen a few people saying that an EMP attack would be more destructive than a nuclear war. It wouldn’t. An actual nuclear war would cause unimaginable devastation. Major cities would be flattened and burned by multiple strikes. Airports, harbors and military bases would be hit. Smaller warheads would take out freeway intersections and rail junctions. Parts of the country would be blanketed in fallout. Dust and smoke pumped into the atmosphere by the explosions would block the sun’s light for weeks, adding cold weather to all the other hazards. Then, on top of that, you’d have the EMP as well. Every weapon would cause local EMP damage, and it’s almost certain that high altitude EMP bursts would be included in the strike to maximize the chaos. A major nuclear war would be a lot worse than an EMP. Short of an impact from a slate-wiper asteroid it would be worse than anything I can imagine.

Good point. But if you do have your drives and at least one very simple computer stashed away in an emp-proof container it will once again become useful when they eventually get the lights turned on again. And make no mistake about it. We will rebuild our civilization. Up to that point, yes, I entirely agree with you that hard copy is easier to deal with.

Do you mean clean it so you can drink it or clean it if the electricity goes out and the pump isn't working? If you want to drink the pool water, the best option I know of is to distill it yourself. I just had a reader send me this same question, and she mentioned checking around marine sites to see if there's a product available to remove salt from sea water in an open water emergency. I do know that the Berkey filters will NOT remove the salt. If possible, you're better off storing several 55 gallon drums filled with tap water and several cases of bottled water. I also reuse 2-liter soda bottles by cleaning them, refilling with water, and then storing them under beds and in closets.
If you just need to cover one person for two weeks in the cheapest way possible, you can buy one bucket for $130 and stretch the 27,330 total calories an extra day or two at 1,900 calories per day instead of the usual 2,275. Or buy two buckets for the cheapest way to cover two people. But we’d recommend a minimum of two buckets regardless, even for one person, just for redundancy and the unexpected.

Over the phone from the company’s headquarters in Salt Lake City, Shields attributed the spike to the onslaught of natural disasters that left thousands of Americans without food in 2017, and rattled many more. “You got the hurricane that hit Florida, you got the hurricane that hit the Houston area, you got the hurricane that devastated Puerto Rico,” he said. “Geologists are coming out and saying that California is severely overdue for a big earthquake. You got these major events that are taking place that affect mainstream America. So how do you protect your family?”
