User blog comment:Ichigostop/Isn't Shanks supposed to already know where One Piece is and how to get to Raftel?/@comment-3362155-20110131093617

I also thought that Shanks would know how to get into raftel and find one piece.But I think it just indicates that One Piece isn't an easy place to go whereas you can just walk and take back one piece.Imagine,let's say that Gold Roger and Whitebeard is on the same age.Then,Roger started being a pirate on the age of 25 for example.Then later on being executed at the age of 50,assuming that he already found the one piece.It just shows that it would approximately take you 25yrs more or less to find one piece.BTW this is only my opinion :D
