Buckets are great, but rats can chew through them. Store them where you think you can protect them from rodents. Also, plastic is somewhat air permeable, so mylar bag inserts are a really good idea. For basics, the LDS site is the best. You can get flour, wheat, beans, rice, sugar and some pasta already processed in #10 cans and boxed by the 6 can case. All my beds are on these case lot boxes so they take up zero extra room in my house. The prices are extremely reasonable since the church only covers its cost. I wouldn’t store anything in garbage cans just because the sheer weight of the thing will be prohibitive…unless you have a forklift lying around!
OK, so you have decided that you want to take steps to protect your family from unseen events. You may not know what events to plan for or you could have a much defined idea of the threats you see, but regardless you recognize a need. There are people who come to the Prepper Journal after they read something on another prepping blog or they may have been visiting our site for a year. The newer visitors are usually just getting starting in this crazy world of Prepping and if they are anything like I was at the beginning, knowing where to start can be pretty daunting. Prepping isn’t the same for everyone but most people eventually look for a simple guideline to follow so I have pulled together this preppers list of supplies.
I’m sure I sound like a tin-foil hat wearing paranoid but … this isn’t some worst-case-scenario (return of an ice-age), this has occurred repeatedly over the millennia, is a ‘predictable’ event (possibly/probably) heading right our way. We’ve already seen the early effects but a ‘decades long’ cooling with massively disrupted agriculture and widespread droughts’ could be on the way (estimates vary from 5-15 years).
Over the years, Huffman has become increasingly concerned about basic American political stability and the risk of large-scale unrest. He said, “Some sort of institutional collapse, then you just lose shipping—that sort of stuff.” (Prepper blogs call such a scenario W.R.O.L., “without rule of law.”) Huffman has come to believe that contemporary life rests on a fragile consensus. “I think, to some degree, we all collectively take it on faith that our country works, that our currency is valuable, the peaceful transfer of power—that all of these things that we hold dear work because we believe they work. While I do believe they’re quite resilient, and we’ve been through a lot, certainly we’re going to go through a lot more.”
Regardless of where you live or your family situation, become a community with others.  Even if your community consists of only two or three persons, these few people will serve as your support group and sounding board for the tactical decisions you will make when things get tough.  In addition, you need at least one other person to watch your back as you will watch theirs.

They will star in the upcoming National Geographic Channel show 'Doomsday Preppers,' featuring Americans stockpiling for the end of the world.

Jim: do you have a book about surviving in the woods? I understand your recommendation to avoid gong it alone, but simply cannot stomach the idea of crapping in a bucket in a boarded up house, surrounded by humans in survival mode who are just waiting for the opportunity to kill me and my daughter and take everything we have.... The diseases that people have, ugh just all of it. We are woods people! Always will be. Far far away from others, far far away from help too... Sigh.
This, of course, is easier said than done. We tend to scale up our living expenses in proportion to earned income, so even in the $100k+ bracket, people living paycheck-to-paycheck are not a rare sight. And it's usually not the big-ticket stuff that gets them: we're far more likely to overspend on all the smaller, habitual purchases, because their cumulative cost is less apparent - and potential savings are much easier to miss. The patterns to look for will depend on your lifestyle and on how much you make, but here are several suggestions for where to search for that 10%:
Lifeboat survival kits are stowed in inflatable or rigid lifeboats or life rafts; the contents of these kits are mandated by coast guard or maritime regulations. These kits provide basic survival tools and supplies to enable passengers to survive until they are rescued. In addition to relying on lifeboat survival kits, many mariners will assemble a "ditch bag" or "abandon ship bag" containing additional survival supplies. Lifeboat survival kit items typically include:
