Burying Stuff

Just like my food storage I use O2 absorbers , that way even if there is a leak it makes the difference secondarily one could seal the box with silicone glue and that would seal it good . Plastic ammo boxes would be impervious to water and along with silicone glue lock it up good .
Face it , if you found your can, breaking it is not an issue .
If some one else finds the can they are not going to hesitate in breaking it.

 

W.B. is correct. You want positive pressure in your cached containers. You don't want to help mother nature. One idea I saw years ago in the original A.S.G. was to cover your containers in fibre glass and resin,. 'course you need an opener.

 

I go with the pvc tubes . Vacuum sealed bags work . And as Natshare said , a decent wire saw will open it up in pretty quick time .

 

So far as hiding stuff ,it would be prudent to have a map.
Something happens to me I want my family to find it.

 

I love caches I have used them alot in the military world and in the prepper world generally short term but I find the very diverse and useful

 

Just be sure that your family knows about the map, the cache and what it contains. Don't be too coy or the map might be discarded. I am reminded of the Sherlock Holmes story," The Musgrave Ritual" in which the members of the Musgrave family have for centuries memorized a series of questions and answers...the meaning of which had been lost.

 

I saw part of the TV show Moonshiners recently and couldn't help but think, "if you don't want the revenuers to think that you are a red-neck, hillbilly moonshiner then don't look like one". I'm reminded of one of my great-uncles that always carried a mule harness with him whenever he went to the still, and if he met anyone on the way he would ask if they had seen his mule. So if you are in the woods checking on your cache have a book on birds, wildflowers, mushrooms, tracking, etc., and be prepared to bore the hell out of anyone you meet.
