I strongly encourage all FReepers to read and apply the learnings in this book:

“One Second After” by William R. Forstchen
It was that book that caused me to finally break down and get a hand cannon (Sig P-220 45 ACP), combat shooting training, plenty of ammo for it and the long guns, multiple bug-out kits, and 30 days’ supplies.
Just like out-running the grizzly, we don’t have to be prepared to live the longest, we just have to be prepared to outlive “them”.
BTW, a metal trash can with lid on a concrete floor is a decent Farraday cage. Also grounding your old Jeep will greatly increase its chances of operating after an EMP pulse. Have the grounding rod go ALL the way into moist earth.
