Ok, I'll bite.
When I was a younger fellow in the mid 1970s, my sister and I carried our rifles on the school bus to school every Thursday.
Those must of been the days,
suggest you real Alas, Babylon.
Oh my goodness, such a good book,
Although I do prefer Patriots: Surviving the Coming Collapse, good read and full of usefull info.
Frankly, if I'm starving, I'd rather have a chunk of gold that may buy me a loaf of bread, than a pile of green paper that used to be worth as much as the gold.
I'de rather just have more stored food than spend a lot of money on something that more than likely won't get me very much when the SHTF. I imagine that things that have actual use will be more value than gold, which is no more useful than a paperweight. I imagine that ammunition would be much much more valuable than gold. I'de suggest not only stocking up on the kind of ammo for your gun but also have a large assortment of other kind that can be used for trade.
