Football culture isn't always exactly as this story depicts, but it gives a good idea of what it is like in Texas (and I assume other places as well) even 36 years later, especially in small towns and at powehouse schools. 
I found the history of Carter High interesting as my alma mater played them a couple of times when I was a student.
I wish the book kept to a more linear timeline however I was able to keep up and enjoyed the listen.
