Bury a gun and ammo for 15 years (and be assured everything still works when you dig it up) [More]I can see doing this with a couple cheap ones in different locations. I've never recommended dying on one's doorstep, or allowing an enemy to choose the time, place and circumstances of battle, and there's something to be said for acting timid and compliant and being the last person anyone would suspect of leading a personal resistance effort.
Of course, if the time comes to dig them up, their purpose will be to procure more...
