I believe I have just as good results with Mylar bags and O2 absorbers. Now any one can do long term storage without spending a lot on vacuum sealers unfortunately I found out the hard way after buying an expensive vacuum packer.I'm a big believer in vacume sealed food saver bags. I keep a lot of rice, flour, beans, etc that way in several stashes at my houses.
I've had the same thought, I'd be sure to put it in unobserved. Nosy neighbors might assume you are putting in a illegal septic system and turn you in. That includes the noise discipline for the backhoe. I always thought having a water cistern would be a good thing to burry (wink wink)I'm looking into the poly septic/water tanks. The possibility of buying and burying a 1500 gallon tank seems pretty reasonable. There is about a 24" man hole to get inside and you are looking at an interior space of about 5'x5'x6' long. It's a little cramped, but looks good for storage of food stocks. Any thoughts?

I was thinking PVC like time capsules.
I think Rickky hit on an important point. I've never buried anything and was reading an article on it from the latest edition of Backwoods Home Magazine... and they brought up the frost line as well. Apparently, the biggest issue (after forgetting where you buried your cache) is the moving ground (from the constant freezing and unfreezing). According to the article, the movement of the dirt around it can significantly damage your cache, even the 8" PVC pipe they used, and could compromise the integrity of your cache. That article was on burying guns and didn't discuss food, but I'd imagine that the mere act of freezing and unfreezing of food wouldn't be good for the food, especially if it happens dozens of time a year (at least in our area) for 20+ years. Add in a compromised container that lets in moisture or insects/moles/etc and you run a high risk of learning a hard lesson when your can least afford it. It would be interesting to hear from anyone that has any experience burying anything above the front line and if it actually had any noticeable impact on your container.If buried below the frost line...
