Registering for trade or release

Superstition Springs Wal-Mart in Mesa, AZ had this book on top of the pay phone when I went to use it. Almost didn't take it, but was intrigued by the label and thought "What the heck." and spent the last few weeks finding time to read it. The subject was interesting and catchy. Too many characters and an ending that became to formulaic made me wish I was done-with-it-already. Too bad because the author spent so many years in research. My Dad will love the book though so I am planning on sending it to Minnesota for him to read and then release there.
This is my first experience with Book Crossing and hope to have another.
Whoever came up with this idea is a genius. A true traveling library...with no fines!! Yeah.
