Update:  Natalie zu Seyn-Wittgenstein of Denmark held the top slot for a while after a very impressive test with the talented Digby.  Riding to music from West Side Story, they performed a mistake free test.  Her score of 78.6 just put her in front of Ashley Holzer.  Isabell Werth and Warum Nicht had their usual strong, accurate ride to  take over the lead before the final group of riders from whom we will probably see some very high scores.
