Sometimes events won't let you just plan...
[But with a little thought you can plan for almost everything.]
I would paraphrase Gaston Rebuffat, a famous French alpinist, "You will always regret fleeing too late, you will never regret fleeing too early."
[And how and when would you decide to folloow this advice?]
Like others, when the big earthquake comes, I plan to shelter in place, but you must be flexible and ready to think on your feet.
[Why would this preclude doing some thnking now, before the fog of stress and questionable information floods your harried decision-making during a disaster / emergency?]
