The public is forbidden to travel below the southern 60th parallel, that is as you move south towards Antarctica. In the 1900's many nations, many countries, allegedly agreed to this travel prohibition to be enforced, internationally. So, it is said that different governments work together to stop people from going too far south for the winter like birds. I'm joking about the south for the winter. But it is said that most airplanes avoid Antarctica. The earth may not be flat but it could be bigger than what we know as normal people. It might be like a fish bowl.
