Here is an adventure worth mentioning. At one time seeking the Northwest Passage was of great importance to shippers and traders, they thought it would shorten the trip to the East since the only routes they had were around either the Horn of Africa or Cape Horn.
Edvin Buregren and Nicolas Peissel have set sail from Sweden and plan on stopping in Scotland, Iceland, Greenland, Canada, and finally in the U.S.A. and their route runs through the ice choked Northwest Passage. A trip I am sure that will take at least a few month and possibly span more than one year.
They are keeping a blog of their trip Northwest Passage on a Shoestring. These are two very exciting things 1) and adventure through a little traveled route and 2) doing it cheaply. This is the heart and thrill of adventure: New places and on a budget.
