I did not enjoy this book particularly as I found it did concentrate a little too much on Baker's libido rather than his journey. His powers of description are weak too, especially for a journalist. So much of the descriptive narrative, when it comes in waves is rather predictable. It was the author's personality that shone through to spoil this book... He does not really travel with an open mind, his dealing with the people he comes across on his travels shows this. Consequently he does not seem to be hugely beneficial from those peoples generosity.
It is a shame, otherwise it could have been a decent read, in my opinion. The political and social commentary come as a light relief from the author's testosterone driven riding. I do think this is a mid life crisis book, so as a young and not terribly macho man it's not for me. In any case, i urge you to wait for the paperback.
Please read Chasing Che for a more sophisticated read with a latin bike flavour, or Jupiter's travels for the definitive bike travelling book. Although If this book was up your street you might enjoy Richard La Plant's Hog Fever.
