I'm so glad to see you say that, and I totally agree! It's good to think about plan B, C D ... Go back to the basics, foot, shelter, water. How will you obtain them if you have to flee your home? If it comes down to that you better have already established good relationships with people you trust, wherever you intend to flee to. Knowing a skill in demand may be the only form of wealth you can take with you.
There is soooooooooo much to think about for the worst case scenario when the kaka hits the rotating air mover. But like you said, better to be prepared (to the extent you can) than not to be at all.
