Just finished "The Lone Star Ranger"
librivox.org but can't really recommend it. As usual, the reading by Mark Smith of Simpsonville, South Carolina, is excellent. Also, if you like classic westerns then Zane Grey, Louis L'Amour, etc. are standard fare. The problem is that the book reflects the attitudes of the time and narratives not unusual for book by Zane Grey 1915 seem unacceptably racist today - there are several throughout the book pointed at persons from Mexico and a use of the N-word near the end. If you can find a modern, abridged, version of this book then it would probably be more enjoyable.
