So, I've been giving some thought you caching a relatively cheap AR, some mags and ammo in one of those large USGI 81mm ammo cans you can get, just in case the SHTF. I know hoppes makes long term storage bags that last up to five years. My problem is, every time I have tried to hide something, somebody always finds it. I had a time capsule that I buried new years eve 1999 and somebody found it! Also, stashed a big jar of pennies on the hill and somebody found that too. So, has anybody else done this? what did you do to mark your spot?
