Yep! That and booze and chocolate!Thought of one more thing- honey/sugar. It never rots and people are so addicted to it, it will probably be more valuable that gold.
If SHTF, society collapsed, and my life totally sucked, I'd be coming after some of that homemade 'shine and a candy-bar or 2.
I'd be packing some twenties and c-notes, I bet we could make a deal.
