Read it about once every three years to see what's new. The motorcycle is the physical platform, the search for one's own meaning is the metaphysical. There is a companion to it (forget the name, but it provides much background, the actual trip route, and other information. If you go to "Amazon" and hit the "If you enjoyed reading..." button, I'm sure it will come up.)
Lila is not as good a read.
Enjoy the trip!
