As a polar explorer it's not easy travelling south these days. Not like it was in the early part of the 20th century for the likes of Shackelton, Scott and Amundsen, whose sole preoccupation was sailing scott-free (unless you were Scott or traveling with him) on the open ocean with nothing to occupy their time but stroking huskies and fellow expedition members or surfing Facebook. No, these days you have to battle your way to the Polar Circle through a never-ending stream of frigid bergs hovering below the waterline ready to sink your chances of making Queen, Kate Middleton and Country proud … in the form of airport security, Immigration and KLM stewardesses.
