User blog comment:Ichigostop/Isn't Shanks supposed to already know where One Piece is and how to get to Raftel?/@comment-3345720-20110131142158

Yep, remember, somewhere in the story line, the world government were saying that Red-Hair is not the type of man who would go and cause a huge ruckus on his own. Ruckus = becoming pirate king. Shanks just doesn't feel like becoming pirate king.
