Hugh's adventures take place within the larger context of Mexican history, making a refreshing change from the often trifling linear narratives than this sort of travel writing can entail. Some of the situations which he finds himself in simply beggar belief, and if you don't want to head south of the border after finishing it you should check for a pulse.
For self confessed petrolheads like me, Hugh's relationship with his car plays on the heartstrings like nothing else can. It's worth buying for the automotive sections alone.
For anyone who ever stepped over the threshold into an adventure, even if it was just in their minds eye, this is certainly a read for you.
If you can stretch to it, go for the hardback, the cover is a work of art.
