It took them four years of hand digging after work each night for usually three to four hours at a time.
Once they got their basement they had a place to store their home grown produce, brine cured meats, etc.... and I suppose in the back of their minds, hide from governments gone wrong.
Wow - that is pretty amazing.
I’m surprised the building inspector gave them the permit! ;)
I was on a project in Indonesia and there was a huge boulder by the side of the road - like 30’ x 30’. They had a bunch of worker’s on it hand drilling holes. The plan was to then fill the holes with clay and wet the clay so it would expand and break the boulder.
I don’t think they were trying to make an obelisk though!
