come to think of it...my 5 acre yard could use some tilling!Just make sure you bury it in a spot that you can cover up, if a cop notices you've been burying shit. They will start ripping up your yard .
Bury at least three feet down. Dig it up when you need it. You will be fine. Ive done this with weed, guns,ammo, money, MRE's and more.
