Once was flown from the UK to Chicago and then to Denver and then a car to Boulder for a one-day meeting, and then back. At Christmas. I have never felt so ill.

Once was flown from the UK to Chicago and then to Denver and then a car to Boulder for a one-day meeting, and then back. At Christmas. I have never felt so ill. Luckily, I'm retired now, but never, never again. Although I actually like the USA. People, food and such.
