Sorry but the following is a bit rambling - just thinking out-loud on the subject.

I wasn't too keen on the idea of sticking an expensive firearm in a bucket in the ground and leaving it there for a few years anyway. I agree that the danger of someone finding and taking the firearm is not a good thing whether it's kids or bankrobbers eitherway it isn't something I want done with a firearm that I own.

OTOH with the difficulty of carrying anywhere it makes some sense to have the firearm stashed somewhere. In the car is a reasonable option that I am currently using but if my vehicle were stolen then .... I think that the vehicle being stolen from a public parking spot is more likely actually than haveing a bucket unearthed from 4 feet of dirt on some conservation land - highway off-ramp type location. The safety of obscurity and having the bucket burried work in your advantage.

Of course if you also include MRE's or PA tablets then you will need to maintain the bucket which will help lead people to the bucket and ruin the obscurity factor. Of course you could bury the gun and keep the items of limited shelf-life in your EDC. Less hassle having someone notice you have a can of spam and some PA tablets then haveing to explain why you are carrying a glock everywhere you go. Not that they should ask since you should be allowed to but ask they do anyway and usualy they are shocked and angered that you do.
