Not a cheesy actor but rather get our Ham Radio Technicians License. Our church is running a 6 week course to get more people able to provide alternative communications for the area in event of a disaster.
My sister and her husband have theirs and it came in handy last winter when we had a blizzard every week for 5 weeks and it was hard to get around.
Once Water, Food and Shelter are taken care of Communication is the next big thing in a disaster. It means being able to call for help and helping others.
Whenever there is a disaster the hams become very valuable people who help coordinate communications efforts which can bring to bear the most appropriate resources to each area.
We'll also have to save up for a transmitter but that is a good goal too.
