My latest article Social Media for when disaster strikes has just been published in the Journal of Civil Defense, Volume 55, 2021 Issue 1 of the American Civil Defense Association for which I am the volunteer Vice President.
On page 18 you can read my article "Children and Civil Defense." It has much information and resources to teach children important civil defense skills.
All are of use to you as a parent or grandparent.
Do not be the leader of your family who, when your children and grandchildren ask you what to do during a disaster, you go blank.
Know what to do before the event.
Do it now.
