There is a quote about travel attributed to the writer Paul Theroux: "Travel is glamorous only in retrospect."
This quote is used by a lot of writers on the Internet, but there is no citation information.
According to Wikiquote this quote is from an interview with Theroux in the British newspaper the Observer (London, October 7, 1979).
I've tried finding this interview by doing research at the library but with no luck.
Can this quote/interview be found in any published collections of Theroux's work?
