I've seen a documentary about the Native Reindeer Herders in the Coldest, Northeastern Siberia. They too had a sort of Reindeer Hide, "Shelter within a Shelter". There may even have been a Third Shelter within this Setup.

We may be referring to the same Documentary, -or we may have seen Different ones. Still, these Shelters within Shelters Idea, -is a very good one. [color:"black"] [/color] [email]bountyhunter[/email]
