This is for the Canadians.
An expedition was undertaken by a businessman Bedaux to drive a group of Citroen Kegresse half tracks to Alaska.
John Huston the famous film maker recorded it on an interesting movie and Bedaux himself is an interesting character. He finished up in a US jail for collaborating with the Nazis on business deals.
The trip was a complete disaster and all but two vehicles were lost (they drove one over a cliff for a film effect when they could go no further and put another on a raft in a raging river to film it disappearing around the bend. A couple were recovered from the bush in recent years.
Here is an interesting clip.
