Interesting article that covers what folks are doing to prep incase a solar storm occurs. The one bit I found of interest was the Surviror Library site. Most of the books are from a 100 years ago, but cover how to survive and build things without modern tools. I see lots of stuff worth reading in general.
The one thing I found that the article didn’t really cover was firearms. They did food/water/electric/etc. But surpisingly seemed to have a lack of firearms (security) involved. Reason I point this out, is you can store all this stuff, but if the world does end, those that have not will most likely come after you for your stuff.
