This is almost as crazy as the couple that went around the world in a WWII amphibious jeep back in 1949 and into the '50s. I had to search the web to refresh my memory. Here is a web site http://members.iinet.com.au/~daveb/halfsafe/halfsafe.html

They actually made it (or he did). She gave up part way. The web site has the story and pictures.

The problem with these insane attempts is that somewhere along the way they get into trouble and endanger other people trying to rescue them.
