Collapse: How Societies Choose to Fail or Succeed by Jared Diamond
I checked this book out from the Saint Paul Public Library. It was among the first books that I had ever checked out from there. It was severely overdue when the 35W bridge collapsed. I really want to finish it.
Diamond set up the book explaining the algorithm for examining civilizations. I was surprised by his addition of a familiar modern society, the ranch communities of the Bitterroot Valley. My good friend lived there for years raising horses and a basset hound and her daughters.
