in RE, you could circumnavigate earth by going north or south far enough. of course, you would pass the north or south pole, so IN A SENSE, you would no longer be going farther north, but back south, or vise-versa.
but Tom Bishop claims that if you went south, you would keep going forever and ever and ever...
other FErs say if you went south you would fall off the edge, or be stopped by the ice wall, or soldiers from "the conspiracy" would force you to stop.
the FACT that many people have ACTUALLY crossed antactica they totally DENY!
they are so blind it's laughable!
