I just read about Rainer Zietlow's two-part natural-gas marathon tour, where He and his Crew will first drive from the Atlantic to the Pacific and then driving from Tierra del Fuego to Alaska in a CNG VW Caddy Maxi.
In October 2009, the Crew is currently driving across Russia.
You can follow the Group's tour, here :

If you read the "Project" section, Zietlow and his team want to see the checkered flag on April 2nd, 2010, in Barrow/Alaska at the world's northernmost natural gas fuel station.
Does anyone know if there actually is a CNG fuel Station in Barrow, Alaska ?
