We left Wisconsin, our new adress: Meribel France, by the way, we took the shack with us :-)
Testing of such shacks (a primitive bomb shelter, which in theory, would be cheap and easy enough for any American citizen to build) occured shortly after WWII. Atomic Shack testing discontinued in 1949 due to lack of funding.
A well taken advantage of shack. Please view in full.
