Did deep earth bunkers go out of business? I'm just watching their show on netflix. It looks like they filed bankruptcy paperwork just last November.
I just found their website. Underground Bunkers & Survival Shelters from Rising S BunkersThey built a nice product unlike many of the others on the market today. There is another company in that area called Rising S Company or Rising S Bunkers that build the same Underground Bunkers made from steel just like Deep Earth Bunkers did.
