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?

My math was not off, since I avoided mentioning the specific distance from the South Pole (precisely because of the difference between a plane, a sphere, and an oblate spheroid). Both Zach, whose math you incorrectly attributed to me, and you have made simplifications to the problem -- he assumed that the distance to the south pole was the radius of the circle, and you, that the earth is a sphere. I simply said that it was possible to find locations that allowed you to travel 1 km east and arrive back at the same point.
