When I was a little boy (in the 1950’s), ‘fall-out’ shelters were the rage. To excape deadly nuclear radiation.
Then as we got older, they became ‘fruit cellars’, where jarred and canned goods were stored.
Now...it’s time to make sure the storage area is weather proof and adequately hidden away.
The problem I see is that most of our storage places are flammable. I'm starting to think that the folks in the mid west - those with tornado shelters - have an advantage. We in CA need to dig out the side of a hill.. or something.
