You should watch Long Way Round. It is this documentary television miniseries thing that Ewan McGreggor and his friend Charlie Boorman put together. They rode from England across Europe and Mongolia and down through Alaska to NYC. They had things pretty easy at times as the locals all recognized Ewan [including the Russian Mob] but the going was by no means easy. Some of the things they overcame were just amazing and things got to be quite emotional for them at at times. It is just amazing. I’ve watched all 7 hours or so of it twice. Their cameraman also is featured in it some times. He is sort of the comic relief and I wish they had more of him in it. I’d love if they released an extended cut or something with an extra few hours of footage as they went across Mongolia and Eastern Europe.
Charlie also did “Race to Dakar” after that. I haven’t finished watching that series yet. And right now on the BBC(?) they are running their latest that they just finished called Long Way Down where they ride down to South Africa. The 6th episode just finished.
All of these (including the complete Long Way Down) should be findable on thepiratebay.org […assuming you already own the copy and are looking their for backup purposes only]
