Quite a few years ago, I worked with an interim consultant who told me a story about when they went on a fly/drive holiday to the US. After traveling from London Heathrow to Las Vegas, they picked up their hire car and headed off out into the desert. The plan was that they would make their way around Nevada, Arizona etc. take in some of the sights, such as the Grand Canyon, and generally take in that part of the world.
At the time they had a really high pressure job, lots of demands on their time and were constantly either on the phone/email.
