There area few things one wants to do in their lifetime. Lots for me; and one of them is taking a magnet to latitude -90S, drop center to the south pole and watching how it behaves.
I came across this page with astonishing pictures of Antarctica, on the Big Picture
And, by far my favourite, this picture of an ice carved cave, titled "Ice Tunnel"
Go take a look at the whole series.. the cold, dark, brooding, star-filled, aurora clothed, ice-covered continent will take your breath away.
And to plan your future travel, IAATO is a good place to star.
