Currently reading On Writing Well by Zinsser. An excellent guide by its own merits, but as an additional benefit, you get to sample writings from other authors. He quotes Alan Moorehead in his samples of travel writings. Checked out Rum Jungle from the library and finished reading it. I do not think, no other author can engage you with a travelogue of such a monotonous place like the Northern Territory in Australia. One thing Zinsser drives home is, it is always about people and blend humanity in your writings.
