The kit I will grab if I ever have to flee contains homeopathic remedies, cash, gold, and my hardware wallets. I know a bit about medicinal and edible plants. Hoping I can stay in my home, I keep spring water in jugs at all times, and have lots of non-perishable foods in my pantry, a whole house generator (and a wood burning stove just in case), lots of coats, blankets, candles, lamps and lamp oil. I know a few tricks to make heaters and candles and can grow my own food.
My biggest worry is not being able to contact my daughters to see where they are. O e of them has instructions to drive to our lake house if shtf, and I will meet her there, but what if she doesn't have enough gas in her car? How will I contact her? I'm thinking of getting long range walkie talkies for that event, but I don't know anything about them. Ham radios seem attractive to me, maybe I'll look into that.
May none of this come to pass, but it's best to be ready anyway.
