Hayes, Bill. “My Journey with the Grandmaster: Reflections of an American Martial Artist on Okinawa.” MP Publishing. 1997.
Review: Although this book is no longer in print and the offered used copies on Amazon are priced so high that it is laughable you can still put your name in for a copy when the book is reprinted by Sensei Hays some time in the future. It is worth the wait and costs. Well written and it conveys a good deal about Okinawan Karate.
I ran across it a while back and managed to get a reasonably priced book for my collection and I have not been disappointed. He and the writings introduced me to some new concepts and fundamentals I had not known of before. That alone made it worth the price of printing, etc.
Honestly, I am not sure how I missed putting this into my Google Martial Art Library but I did. I am fixing that mistake now. Get a copy when the price is reasonable or when it is reprinted.
