Sue, awesome effort - as usual! You are a real asset to the forum.

Quibble: everyone states sound general principles, but what is the specific circumstance / information / data point that would trigger you to flee?

Fire upwind and five miles away? 2 miles away? one mile away? half a mile away? Next door?

Tsunami or flooding: predicted? warning given? visible on the horizon?

Etcetera.

Are you going to wait to make a situation specific decision or have you figured out when you need to flee on some objective basis already? What criteria will you use to make your decision? Are there objective criteria?

What information source or sources would you trust?

To try to beat the crowd, do you take the time to pack or go with your BOB and whatever is in your vehicle at the time?

Go, Sue, go!
