As the title reads that is what this book is all about. Lots of good information and details. A little boring stuff mostly with a few interesting stories. I was hoping for more of the interesting stories but it is what the material is. It became repetitive at times because each border was discussed for each state and with 4 borders mostly for each state, heard the same basic story each time.
I will be posting it on PBS, I think there are 4 WL for it.
