yep pretty amazing...Good friends of mine decided to sell all and travel the world by sailboat...they left in 2006 and will return in 2010.
They created a website they update now and then and part of that is a GPS tracker of all the people doing the same damned thing...or simply travelling the seas. Blew my mind!
Anyways heres Stevens blog...Im sure youll enjoy some of his stories as well.
