Query: "Jake Adams 50 years later"

I first read this book 50 years ago and still think that it was one of the best books that I have ever read. I had never heard of "Bird" or "Pres" before reading this book. I always wondered what city was the basis for the urban setting depicted in this book. Since there is a Lincoln University near Philadelphiia I wondered if the book was set in Philly. Then I discovered that the author was from the St. Louis area. I am currently reading "Miles" and he mentions that he played with "Bird" and "Pres" in East St. Louis, IL and there actually was a Street Gang called the Termites there. So, I don't have to wonder any more about where the book was set.
