Query: This book wasn't helpful at all.

I bought this book to prepare for my first show season. I flipped through it and was immediately impressed at the seemingly varied amount of information included. Once I sat down with it and read it cover to cover, I had learned very little beyond what I already knew.This would be a good book for someone who hasn't started riding yet, but then again, why even think about showing before you've even started lessons? Hunter Seat Equitation, by George Morris would be a much better investment that would get you closer to winning in a show ring faster than this book ever would.
