If anyone else is interested in doing some bike adventures in Bolivia (or Southern Peru for that matter), PM me or check-out our web site www.gravitybolivia.com and email us, Eric kindly left a couple of his bags with us, and we have more than a few bikes lying around that would be great for these kinds of adventures.   If anyone has more random questions about biking in Bolivia or Peru you can also just get in touch.  Cheers.
