Another stamp from Emma's passport testifies that the trip didn't put her off the US altogether. "My boyfriend Dillon and I went to San Francisco in 1993. We hired this incredibly sporty car, a Ford Probe, and drove through the redwood forests of Northern California - there were some really strange-looking houses there, completely isolated and self-sufficient."
Emma's travels then took her to Idaho, in an attempt to trace the Oregon Trail. "There were valleys where you could still see the wagon ruts made by the original settlers who'd come over the Rockies - these huge tracks in the ground where the earth has never been ploughed since. There were little houses that had been built just for one winter, and plenty of real cowboys hanging around," she says.
"I never realised how addictive driving could be until I went to America. We covered 4,500 miles. The landscape is so extraordinary, you just need to keep driving to see what's over the next horizon. One minute you've got the volcanoes along the Pacific sea border, next it's lush valleys and national parks."
But Emma's real holiday romance is with a place much closer to home, where she doesn't need to pass through customs. "I usually go to Cornwall for holidays. My mum's got a house there, on the Lizard. I love leaving London on that elevated section of the motorway. It's usuallyaround sunset and I get a great feeling of being some sort of pioneer - leaving behind this great, buzzing city for the countryside beyond."
