Advice for everyone.
If you have a high water table don’t bury. Look to the trees. PVC wrapped in camo realtree over 40 feet in the air will not be seen if you do it right. Paint the PVC Dark brown, seal it and attach it with WIRE to the tree. NOBODY searches the tree tops. Must be out of reach of a standard ladder. Look to the center of a Vee in the tree trunk high up. Dense cover of branches even in winter with no leaves. If you can shelter it under another large branch that would be better. Shield it from view from the ground and from overhead observation (drone/copter)
Multiple places, and don’t tell anyone. Loose lips sink ships.
FYI, Single shot shotguns and a stash of slugs and buck will be fine. All you need is the 1st shot to get your next gun from them later.
Sadly I am unable to do this as I don’t have any guns.
That is interesting and might work until a storm brings the tree down.
That will also work.
Below ground level but above the water table or elsewhere.
There is no point in leaving guns in one place, ready to be confiscated.
