Essay: "Why We Travel" by Pico Iyer

Here's a link to an essay by the much traveled Pico Iyer, well known for his essay, "The Nowhere Man" (if anyone has a link to this article in its entirety let me know).

Is this indeed the heart of the impulse to travel, to be in search, as Iyer states, "of something...(even) if it's one that you can never quite find?" Meanwhile the "something" gives way to something else, as the essay goes on to say, in a search "undimmed by familiarity" where we are "ready to be transformed." I'm curious if others think this a fundamental aspect of their travels abroad, and indeed travels not abroad as well, as the article touches upon.
