Road Fever by Tim Cahill Black Swan, $116 Clicking on amazon.co.uk to find the cover shot for this reissue, an advertisement says yellow fever shots can be obtained at a walk-in clinic near Finchley Road tube. This is probably important, as the website for the Centres for Disease Control says 'yellow fever is enzootic in certain sylvatic locations in South America', whatever that means. It's not clear if Tim Cahill had his shots for Road Fever, a south-north drive through the Americas with endurance driver Garry Sowerby in 1987, a publicity stunt for General Motors' relaunch of the Sierra pickup aimed at the 'upscale cowpunk'. A writer for the New York Times Book Review and editor-at-large for Outside magazine, Cahill lives in Montana and from there concocts some truly weird travel stories - Pass the Butterworms, Jaguars Ripped My Flesh, A Wolverine is Eating My Leg. He has been called an 'Explorer with a capital E' who 'balances a sense of peril with playfulness', although the proliferation of packaged adventure means he had to add 'life-threatening danger' to his repertoire, going where guides can't get insurance. But that's another story.
