James Salter discusses the relationship between writing and travel from an old Paris Review interview:
INTERVIEWER: Does the travel help your writing?
SALTER: It’s essential for me. There is no situation like the open road, and seeing things completely afresh. I’m used to traveling. It’s not a question of meeting or seeing new faces particularly, or hearing new stories, but of looking at life in a different way. It’s the curtain coming up on another act.I’m not the first person who feels that it’s the writer’s true occupation to travel. In a certain sense, a writer is an exile, an outsider, always reporting on things, and it is part of his life to keep on the move. Travel is natural. Furthermore, many men of ancient times died on the road, and the image is a strong one. Kings of Arabia, when they are buried, are not given great tombs. They are buried on the side of the road beneath ordinary stones. One thing I saw in England long ago struck me and has always stayed with me. I was going to visit someone in a little village, walking from the railway station across the fields, and I saw an old man, perhaps in his seventies, with a pack on his back. He looked to be a vagabond, dignified, somewhat threadbare, marching along with his staff. A dog trotted at his heels. It was an image I thought should be the final one of a life. Traveling on.
