MY EARLIER SURVIVAL-KIT POST caused reader Fred Weldon to recommend including toilet paper, which may be in short supply: “After all, if you’re gonna eat, you’re gonna excrete.” Good advice. I do keep a roll in my kits, and also in each car. And Target sells purse- or backpack-convenient mini-rolls, from Charmin. Those also fit nicely in a glove compartment.

Reader Michael Fisher, meanwhile, suggests this kit, and wonders why I didn’t mention a gun. Well, I figure most Insta-Readers have their own preferences in that department already.
