A couple of travel media that Dennis recommended for those who enjoyed Into Thick Air:
Attending Marvels: A Patagonia Journal, by George Gaylord Simpson
A TV travel series on the Science Channel (SCI): An Idiot Abroad. If you Google it and go to the show's website, you can see some clips from the shows.
