The only people who aren’t living with us who we’ll take in is my college age kids. They are in apartments on their own with very limited budgets and simply CANNOT make the kind of preparations necessary. What I’m doing, I’m doing with them in mind for the present.
When they are finally self-sufficient, I will have a good long talk with them about preparedness and they’re on their own at that point.
It is so easy to have a small store of non-perishable food that will be enough to get you by for a couple months.
I've got 6 months worth of food for 3 at 2,000 calories a day. It all fits on a standard sized shelving unit, albeit a bit tightly.
Water was an issue, but where I live I think we've got that covered.
Good luck to you.
