This discussion seems extremely hypothetical. Who among us has actually packed up and left in the face of an impending situation? What was your experience? Was it the right move? Would you do it again? What words of wisdom do you have or the rest of us?

On two occasions, faced with wildfires, I had the car packed up, ready to drive away. Didn't pull the trigger, though, so I have little to offer.
