Emergency one-person survival stove- the best choice is alcohol, 91% of the time.

So, we have trail equipment stores, hardware stores of various types, liquor stores, drug stores, convenience stores, grocery stores, boating equipment stores and marinas as possible sources if you’re afoot on your own. That’s pretty versatile. I don’t think any other liquid fuel comes close, unless you’re willing to use automotive gasoline, which requires special stoves and a lot of ventilation and there’s still danger.

The Urban/Suburban EDC/Get-Home kit list

I’m a firm believer in versatility. The more detailed the scenario, the more specific you get in trying to predict the future, the more likely you are to be wrong, so I believe in just generally enabling yourself to handle more situations as they come up. Knives, flashlights, and multi-tools are among the most versatile tools there are, and can make you a whole lot harder to kill in a “collateral damage” sense. Insulation, water carrying capacity and the ability to make fire are almost universal needs.

Aquarium tubing as survival gear

This is an odd survival item in that I’ve never had any use for it in an urban or suburban or even rural environment, only in the woods and mountains, but for there I find it indispensable. I never go out for more than a day hike without at least six feet of aquarium tubing, preferably eight or nine feet, and I’ve used it for more decades than I care to count.
