Earth Sandwich

In May, (b/v)logger Ze Frank put forth the wonderful challenge of the Earth Sandwich. You take two pieces of bread, place one of them on the ground, and then place the other at the antipodal point. Given that so much of the earth is water, putting both slices on land is not that easy. (A good map is here.)

Congratulations to brothers Jon and Duncan for completing the world's first Earth Sandwich. They went with the New Zealand-Iberian Peninsula sandwich, but as far as I could tell, both pieces of bread were not laid down simultaneously. Any one up for a trip to {Hawai`i or Botswana} or {Borneo or Brasil} or {Tierra del Fuego or Lake Baikal} or {Greenland or Antarctica}?
