One of that era's icons remains — a massive underground bunker designed to protect all 535 members of Congress and their aides against nuclear war. Dug into the Allegheny Mountains at the Greenbrier resort in White Sulphur Springs, W.Va., it once had 75,000 gallons of water, a power system, medical and food services, 30-ton blast doors, art of the last days of Pompeii and a mural of Washington scenery that was capable of changing leaves on the trees, depending on the season.
Of course, it goes both ways: you will almost certainly find it harder to get help if your neighbors still resent you for puking on their doormat and constantly partying at night; so once again, not being a jerk to other people is not just good manners, but a very legitimate survival skill. Even if it's not really your nature, say "hi", engage in small talk, and offer to help with minor hurdles every now and then. Bring your neighbors a pie or some donuts, add them on Facebook, and try to find common interests. Socialize with coworkers who live nearby, too. Even if the zombie apocalypse never comes, it still won't be a waste of your time.
In the end, it’s a good thing to have multiple tools or ways to accomplish something. Most preppers take a “two is one, one is none” approach with backups and redundancies. Following this guide is an efficient way to have those backups. Rather than having three med kits in your basement collecting dust, each one is serving a purpose at all times by being ready in your home, bug out bag, and get home bag.
Canned meat, veggies, or fruit. Storage life in excess of 20 years (regardless of "best by" dates). Tasty, relatively cheap (~200-300 kcal per dollar), and the choice is pretty broad. Fruits, veggies, and soups are not very energy-dense (~200 kcal per pound), making them impractical for hiking or bugging out; on the flip side, the syrup may provide some additional hydration. Meats fare much better, tipping the scales at around 1,500 kcal per pound. Canned foods are a good option for longer-term planning, provided that you have enough shelf space.
Bombs rain from the skies, alien ships descend with lasers ablaze, improbably proportioned, irradiated sea monsters tear through essential infrastructure. You'd think that running, screaming, and finding clean underwear would top the list of activities likely to improve your chances of living, followed closely by finding a sustainable food source and offering sexual favors to the person with the most impressive arsenal. Unless you were a prepper, in which case you'd be worrying more about the safety of your cigarette stockpile.
An argument can be made that even in an emergency, potable water is never too far away; after all, most human settlements have been erected near natural reservoirs: rivers, lakes, or easily reached underground aquifers. But this is an oversimplification. In rural areas, water supply can be fairly meager and vulnerable to weather fluctuations and other cyclic phenomena. For cities, it is true that many of them are seated on the banks of major lakes or rivers, but suburban sprawl can easily put some residents 10-20 miles away from the nearest reservoir; on top of that, some of the 20th century settlements in semi-arid and desert climates rely on water hauled from tens or hundreds of miles away.
I think the point of the quicky foods like the ravioli is actually good thinking. You may not have access to water right away, or run out. The other foods require water to cook. I have thought about that issue myself. what if you don’t want the whole neighborhood coming to your house when they smell the food. Precooked canned food can be eaten cold. No smells in the air to give you away. Think about that one. Please.
