Many years ago, comedian George Carlin did a stand up routine called “stuff”, that had a grain of wisdom in it about prepping.
He started out by describing your house as “a place to keep your stuff”. Then, when you travel a long way on vacation, you take a subset of your “stuff” with you. At your destination, you take an even smaller subset of your “stuff” as you go short distances. Finally, for the briefest of trips you take only your “bare minimum stuff” with you.
But this also applies to prepping. If you are staying home, you have all your prep things with you. But if you are evacuating, yet have time to evacuate, you still take a lot with you. Yet if you have only an hour or two to get it together before you go, a smaller amount still. Finally, if it is “grab a few important things” and dash out the door, you have the bare minimum you need to survive.
Now this being said, it is a major help if you have enough organization ahead of time to have different “manifests”, based on the situation.
And I imagine that most preppers don’t. They may have a good “whole house” prep set up, and maybe an evacuation manifest, but they might not have either a “two-hour” prep list or a “grab a bag and head out the door” manifest.
And *this* is your opportunity to give them a gift. It is as much giving an idea as it is giving “stuff”, but if you want you can make them a kit for the prep they haven’t yet made, but should.
Here is a good, but long video on a “Every-Day-Carry” urban carry bag. Probably too personal of a thing, but perhaps could get them started with a decent backpack (I prefer getting a nice clean one at the thrift-store for $6 and shoving it in the freezer in a bag to kill any cooties first!)
But then could fill it with all sorts of basic useful things like a small flashlight, lighter, first aid, etc.
