Jackfruit

I really admire this Viet-American guy. He twice trekked through South America on his bike. He deliberately avoided developed areas, exploring places where tourists normally won't go. His blog about his journeys is fascinating (Click here to his blog
http://davesnewadventure.wordpress.com/). He even published an online book called "Jackfruit" about his adventures, detailing his contact with native tribes in the Amazon jungles. Look it up on amazon.com. He used to distribute it for free, but later I think a publisher got interested in his book, so I suppose he pulled it off line.

I wish I had done something similar back in the college days.
