La Mitad del Mundo ("The Center of the World"). In the summer of 1998, Craig and Betty stood on the equator near Quito, Ecuador in South America. Craig is standing in the Northern Hemisphere and Betty in the Southern Hemisphere. As you can see there really is a yellow line circling the earth at the equator! Thirteen years earlier we stood in the Western and Eastern Hemispheres at the Prime Meridian in England.
