On my recent Baja tour I ran into Dominic. He was riding a tandem from Alaska to Patagonia - by himself - picking up random passengers along the way. He was a really nice guy and he is making a film about the experience.

I took a short video of him and posted it on you tube: http://www.youtube.com/watch?v=yzpGdhjuag0
Good luck Dominic!.......
