Underground Shelters

No.125173 View ViewReplyOriginalReport
I was thinking about building my own underground shelter.
not sure if I should use shipping containers or concrete I have an area large enough to use say 2 shipping containers width wise as my space is limited.

I did find this online but $80k for a shelter is a shit ton of cash.
