I sometimes feel that if your book sells more than 20 years, then there's something in it that you can say, gee, I did something that endures, that's timeless.
When you are on tour in the UK it takes a few hours to get anywhere. A lot of the time you can have a beer, close your eyes for two minutes, and then you are there. In the U.S. it is much more like a road trip as all the cities are so spread apart.
