McMurdo Station, Antarctica
Saw, Shovel, StayThis might not look like a happy housewarming, but given a flat white field of snow, these tools and a couple bags of survival equipment provide exactly what you need for reliable and potentially life-saving shelter in Antarctica.
"Happy Camper" (aka, snow school or outdoor survival training) was one of the requirements for my contracted work supporting the US Antarctic Program. We learned all sorts of skills including sawing snow blocks for quinzee huts, building trenches to quickly get out of the wind, melting snow for water, setting up tents, understanding the symptoms of hypothermia, and all sorts of survival techniques to stay warm and healthy until help arrives.
This course was critical to learning how to STAY protected from the harsh continent.
I still cannot understand how Shackleton and his crew survived so long in the frigid outdoors, but I am confident that I could make do for a week or so!
