One of the Pig Traverse Sleds

The 4 tractors on the traverse are going to leave Byrd Camp, where we're
at now, and head to PIG camp. 4 tractors, 7 people, 7 days. It took 6 Herc
flights to get this stuff here but thats as far as the Hercs will go in
Western Antarctica, so the rest is going to reach the camp by glacial
traverse.
