I'm a new landowner, and I can't wait to get hiding stuff.

I'm interested in having a lot of my tools and prepper items in easily accessible places like the garage or in the house, but I'm interested in hiding some stuff around the property, and eventually in the wilderness.

These are some scenario's I could think of that support the idea of hiding stuff.

1. Your house burns down accidentally, or is torched by looters.
2. Looters hit up your house
3. Your house is taken over by well armed individuals and wish to help themselves to your supplies

I'm thinking underground is one of the best options, but how? I have read about using a capped PVC pipe as a waterproof underground storage receptacle.
Another good tip I have heard of is to have a certain amount of your stash readily find able, in order to encourage any would be looters to stop looking and make off with what they have found.

Any ideas or philosophies to follow?

I would cut the plaster board out behind a poster or a handing picture cloth, out of sight out of mind. This will make it easy for you to grab in a hurry. You could have an knife or gun behind picture and people will walk straight passed it even if they were looking for the gun.

If you store stuff out side it better be bone dry or your going to get molds. I have a old green house with just a tarp over it to store stuff, mostly in rubber made tubs, and moisture got in. Books ,clothing. and any leather got moldy, metal rusted.

Sorry, but for me, a good hidey hole should not be discussed any time, any where. It defeats the purpose if everyone gets educated on what to look for. Just try to think outside the box on this one.

YUP!
Second that.

I think you're thinking about caching? If you do that, the tools are not so easily accessable on a daily basis. If you do choose to do that,one idea is to put your stuff in a big plastic tote wrapped tightly in plastic and taped shut (buried not in a flood prone area). Also you might want to plant something different but not too different on top to find it later (raspberry bushes maybe?).
Other ideas for hiding stuff outside in a building....
-in the attic (in a steel box)
-if you have panelling instead of drywall you could leave one piece slightly less fixed to the wall and hide stuff behind that
-hide it in a box marked "donation" or "old sewing stuff" in a pile in the corner (Thank you to James www.thecovertprepper.com)
Clearly fire presents a bit of an issue for many hiding places, I don't know how to get around that aside from a fireproof box.

I hear the folks that do not want to discuss hiding places, and I think I have enough imagination to come up with some creative spots so I don't necessarily need to hear about yours, but I'm interested in some discussion surrounding pros and cons, pitfalls, opportunities, etc. I would think an added dimension to caching is worrying about maintaining the supply, keeping it in good condition, etc. just adds time and effort.

On the other hand, what basic things should be hidden and not just put away in the closet.

slightly paranoid are we. Mothers are great at hiding stuff, like the box of cookie or that newly bough item. I'd hide food, but it better be bear and mice proof and weather tight.

I just love 5 gal buckets. Here is my new favorite site,

A sailboat made from buckets?! I'm in!

if you want a few ideas....

Beth, a little paranoid, but mostly think the squirrels have it figured out. The five gal. bucket seems to be the perfect caching vessel. I'm wondering where you can get these buckets for free? local restaurant maybe?

For food safe buckets try restaurants, ice cream places. But for storage of any packaged foods or supplies I use 5 gal oil buckets, washed out of course. They are not food safe but no food is ever in contact with the bucket. Just rip the lid keeper strip off, pop the lid, give it a good hot soapy water scrub and dry completely.
