Why does Secretariat bring tears to our eyes ? A little less than perfection can make us smile, but this horse ("horse" is such an understatement)is so emotionally overwhelming, some of us cry. Although I haven't read the other books listed here, "Secretariat" by Raymond G. Woolfe may be the definitive book about this unique champion. There are details that put the reader at the scene and in the action. In the back of the book are special features: Secretariat's lineage (his bloodlines), his winning get (progeny), and biographical sketches of what happened to the significant persons in his life. (This feature of the book is especially interesting if you've seen the movie.)There is a copious supply of pictures, both black and white and color. If you buy this book, allow an hour just to look through it, then read it to relive vicariously the days of horseracing glory. I have the original newspaper page about his winning the Belmont,which I had considered selling. I think not; it's a physical means of contact over the years with a magnificent creature. This is a fulfilling book for anyone who loves horses, especially this one.
