Omnity,

Have you seen the Ribbon of Road web site?

"On July 26, 2005, Brooks Allen & Gregg Bleakney embarked on a 19,500 mile bicycle journey from Prudhoe Bay (the most northern road accessible point in Alaska) to Tierra del Fuego, the southern most tip of Argentina. Their goal is to raise $50,001 to help fight Diabetes"

Bleakney completed the whole trip, and it's documented on the site. Words don't do justice to the photos he took. The Bolivian salt flats are unworldly.

Check the album at Stage 3, Part 5 for the salt flats.
