Stocking up food, that's a different story.
When I was little right around 1960 for about five years we really did keep the old sears and monkey wards catalogues in the johnnyhouse. It was not for reading because nobody wanted to stay a moment longer than necessary with that open pit a couple of yards under your sitter. Those thin mailorder papers in the middle were the best.
Of course when we were in the woods we used big elm, sycamore or water oak leaves.
We used corn shucks and the privy was very near the corn crib. I always wondered about that. That out house was never located properly. It was always too far away in winter, and TOO CLOSE in summer!
