While not a novelist, some of you may enjoy Paul Theroux's books based on his travels thru South America, (The Old Patagonian Express), China (Riding the Iron Rooster) -- note: he used the trains and other travel modes that the local folk did, The Happy Isles of Oceania (paddling a canoe thru the various countries/islands of the SOuth Pacific), The Pillars of Hercules, and one of my favorites, Dark Star Safari (his train and bus trip thru Africa -- a really good book).
