Your post is like a Christmas Gift to the list.
THE Harry Vititoe's relative! How exciting! I recognized your last name immediately--as any regular to this list would.
Welcome! If you can get either books mentioned in the other post you would absolutely enjoy them. The Walter Farley book is all over "e-Bay" usually, you could get a used original hard cover edition. I only see the paperback in the stores anymore, don't think they produce the hard cover anymore (anyone else know?).
The Cooper and Treat book is the best! Thanks to friends on this list, I was able to get one. It's not cheap, but esp. for YOUR family history it would be worth it.
If your Great, great, great, uncle hadn't done such a good job starting Man O' War's career out on a successful note--maybe we all wouldn't have this web page! A great breaking and initial training can't be underestimated, as anyone working with good horses knows.
Hope you enjoy this page, it has the nicest people all with a common interst in the greatest racehorse.
