"It's not hard at all to bury weapons and ammo in the woods for years with zero issues if you're careful. There are plenty of guides I've seen on the internet, even Cheaperthandirt.com has a big tube designed to be buried and it can hold a couple AR15s.

Of course, you've got to remember where your stuff is :)

I've toyed with the idea of buying a couple really cheap guns, like a KelTec rifle and pistol and burying them with some ammo and other stuff just in case... But I haven't been able to find the extra cash just to buy a gun so I can bury it."

"Ah...perhaps one of the biggest problems...money!

I suppose you could pick up a cheap double-barrel 12G and a few boxes of shells? Throw in a cheap cloth bandolier to hold the shells when you take it out, maybe a Machete or a Tomahawk for CQB, perhaps a belt loop for the tomahawk, a decent survival knife...er...that's starting to get expensive and there aren't even 7 days of MREs in there yet...or a coupla rolls of super-soft luxury TP, a few chocolate bars, a canvas bag to carry all this stuff...Hmmm..maybe just the shotgun and shells in this hole?"

"The question is are you buying supplies to fill the hole you just dug, or digging a hole to protect the supplies you already have or plan to have."
