The old Polar Bear Problem:  You go somewhere, set up a tent, walk a mile
south, walk a mile due west, shoot a bear.  Then you drag the bear a mile north
to your tent & have him for dinner.  What color is the bear?

The sequel:  (1) From how many points on Earth (assuming it's spherical, etc.)
		 can you make exactly these moves, i.e., walk 1 mile south, 1
		 mile west, 1 mile north, and be back where you started?

             (2) Describe all of them.
