Ammo storage and cache-ing

[upgrayedd]

-sorry for the confusion, but this appeared under a different thread somehow?????

We all know that when it comes to stocking up on ammo and supplies, you are most likely and probably relying on defending your home and staying put there(because it would be impossible to haul around a ton of ammo food and water)
What is the best way to cache or store ammo? Where to stash it from prying eyes? Same with water and food?
Someone earlier made a suggestion that these supplies be "buried" or kept in "sectional incrememnts" for easier access. I would also think that if someone found one of the stashes, your whole supply would not be lost?

I dont have a basement( a true basement) but I do have an attic and a newer poly shed in the woods behind my home.
How well do ammo cans work? How much moisture will they repel? How long will they keep their seal for? Will dessicant gel packs work well as "insurance" in ammo cans to keep the moisture away?
Can ammo cans safely be buried? for how long?
