Just trying to get out of Nebraska after the eclipse was an eye-opener for me. And I had enough gas to get all the way home without refueling....

Evacuation has the problem of being unable to spread out the movement over time. And people aren't real good at following orders - especially those who are told to go first. Just look at the airplane boarding process at the airport as a small scale example.

The aware prepper will get out WAY early. God bless the public safety folks who stay behind to shoo everyone else out.
