"Now lets talk about Antarctica..."  

Time there gets interesting, simply because you can cross
so many zones in a small linear distance...  but the interesting
problem is this: When you are at the Pole, every direction
is north, or 000 (recall the color-of-the-bear riddle about
the other Pole).  So how do you fly out?  If you pick any
of the 'norths' at random, all but one of them lead somewhere
other than McMurdo -- and not places you want to go.

The conventional fix to the problem is to superimpose a grid
over the true geography -- graft a piece of the equator
over the pole, so to speak.  Grid north is generally aligned
along the Prime Meridian, so grid south runs along 180,
grid east up the 090 meridian, etc.
