A few good quotes from the piece, from two of my favourite authors:
"A good travel writer can give you the warp and weft of everyday life, the generalities of people's existence that are rarely reflected in journalism, and hardly touched on by any other discipline. Despite the internet and the revolution in communications, there is still no substitute."
"Old travellers grumpily complain that travel is now dead and that the world is a suburb. They are quite wrong. Lulled by familiar resemblances between all the unimportant things, they meet the brute differences in everything of importance."
