What is SSOTA (Storm Shelters On The Air)?

SSOTA is a group of amateur radio operators
who practice their emergency communications setup
inside of a storm shelter, or fallout shelter.

How did SSOTA come about, and why?

The thought of SSOTA was created by
a commenter on Ham Radio CQ's YouTube Video
Then I (K4NFP) decided to make it an actual thing, and Ham Radio CQ, liked the idea.
Now, SSOTA is meant to be a group who encourages emergency communication preparedness in the case of any hazardous weather, and our nuclear warfare.
