Out for a walk (Posted on 2002-05-29) Difficulty: 3 of 5
There are some points on Earth for which the following is true:

Starting from one of these points, you can walk 1 km South, then 1 km East, then 1 km North, and you will wind up back where you started from.

One such point is the North Pole. Where are others?
