“move as far as you can from heavily populated areas. If you do not make that happen it is a waste of time to make further preparations.”
That’s the first thing you do. The second thing you do is refuse to respond to FEMA or other government questionnaires.
I get to tell an anecdote about when I “got it”.
Many decades ago I was a youngster and worked for the US Census Bureau in their regional office in Dallas, Texas.
I was good at it and quickly became a crew leader and trainer for my team and others.
One of the mantras we were told and told the public and I told my trainees was:
“U.S. Census Bureau information is confidential and has never been released to other government agencies.”
I believed it—I had no reason not to believe it.
Alas—it was a lie—discovered by some academic types in 2000 searching in dusty archives...

This secret was kept by thousands of people for almost sixty years.
Remember this anytime anyone tells you “they couldn’t have hidden a secret that so many people know about for so many years”.
Yes they can—and they did.
In this case it was in the interest of none of the participants to become a whistle-blower.
