A great resource for anyone who travels for their job, or even for leisure. There are lots of take-aways and the consistent reminder that appropriate preparation prior to travel is the best defense from finding oneself in a shitty situation that could have been avoided.
I really liked the "Review" sections after each chapter which helped to reinforce the concepts discussed, and even included some real-life examples of how the principles were (or were not) followed.
If you have any plans to travel outside of the US (or maybe to a semi-permissive part of the US), you should read this book.
