I’ve got a gallon of chlorine bleach that can purify a few hundred gallons of water from the lake at the end of my street, a crossbow that can keep us fed for a while, and a smoker that can preserve meat. I do know how to properly can veggies to keep them preserved, but I’d run out of lids after a season. I suppose I’d save seeds from this years garden and grow a lot of winter squash next season, but cross pollination might mess that up.

Depending on whether or not I ran into a marauding gang of savages, I could probably make it longer than most.
