When I was 22, I went down to visit my grandfather on his farm. It was my wife's first visit there, and we'd taken pistols because it was where I learned to shoot. Granddad always kept a Beretta .22 on a peg by the kitchen door, and his 1911 on top of the fridge until bedtime... so it was normal growing up there to see firearms.
We get there, and .. both are gone.
Asked Granddad about it, he said, "We hid them because we weren't sure about her (nod to new wife) thoughts on guns and we didn't want her thinking we were barbarians." At that point I mentioned she was just starting to get into shooting.... and Granddad took us on a tour of the farm.
He walked into the barn, and slapped his hand on the top of one of the wall panels... and it dropped open on a hinge and a 12 gauge pump fell into his hand.
There was a hidden panel in one of the produce storage rooms that produced another handgun.
Behind the seat of one of the old broken down trucks was a rifle.
It went on and on...
Finally, I asked, "Why?"
About ten years prior (say, around 1970ish) a group of bikers had rolled into one of the farms just down the road from them and taken the husband and wife there as slaves. It took six months or so for them to get a message out and the police to find out about it. After he and Grandma talked to the couple and got the details, he decided that he'd plan ahead for such things.
I'd spent my summers out there as a teenager... and for at least 5 years, maybe more, there were these "family secret weapon caches" that I didn't know about at all. It was kinda weird to find out about it that way.
