Dec's rambling makes a further comment here:
At the end of the show they show their coordinates as being 78° North. That is 12° and about 800 miles short of the true North Pole. Of course one could argue that they could had gone to Magnetic North, which moves and that is exactly where they did go. Unfortunately they did so 11 years late since they conveniently choose (sic) the position of Magnetic North from 1996, it is currently around 82° or 83° North. It was a bit disappointing, really all they did was go for a long drive in the snow to an almost random point 400 miles away.
