…Is a good one, I think. I found after I read this book, American Nations, I had a much better appreciation for decision made by people from different regions of the United States, once I had a better understanding of the culture and background of each “nation” and how that affects their thinking.
If you are curious, this is a good article that summarizes the ideas in the book:Which of the 11 American nations do you live in? – The Washington Post
The book is good, though. Worth a read.
