I realize how much [Mark] Twain fabricated things. I like it very much, but it's only half true. And it shows what he was trying to do, which was just entertain. Which he does very successfully, though the humor is almost dated now.

Paraguay has had a U.S. supermarket boss as its ambassador for a while. He did the job well. He was there because he wanted to be there. Rather than the British diplomat who didn't want to be there.

American travel writing is very healthy. I'm always flicking through the reviews and I see plenty of travel writing - and an impressive line up and continual demand.

It is a gift, and you realize as soon as you cross the border into Paraguay, as I did, the first time in '82, that you are in a sort of wonderland. Nothing is quite right: the buildings, they've got their own architecture, their own language; and everything is just a little bit off key.

When McDonald's opened up in Moscow - I happened to be there when it opened and wandered in. And the Russians were queuing three times around the block to get in. And when they got to the head of the queue, they'd go, "I'll have a Big Mac please. Have you the cheese and the rolls? And do you have the meat and do you have the salad?" And everybody asks this because they are so used to things being awful that it took them a quarter of an hour to order a Big Mac.

I wonder if this reason is partly geographical, that talk radio is so much more successful in North America than in Britain? People who are very remote - I'm thinking of Newfoundland - feel very connected though the radio.

I don't want to sell other people trips! I want to be there!
