Surviving in Siberia for 40 Years

Smithsonian magazine has an interesting article about a small family which escaped Soviet anti-Christian persecution by fleeing into the wilderness of Siberia. They stayed unnoticed for 40 years, with only the tools and clothes they started with and could make from scratch in the forest. They were so isolated they did not even know there had been a Second World War, much less that people had walked on the moon.
