Part 2: One horse spooks at a colored rail and David explains how horses react to different colors and how course builders use this to take their eye off the top rail to increase the difficulty. He counteracts this in his own program by constantly switching brightly colored rails. One rider works on her tendency to plant her hand on the neck to jump which is interrupting her horse's technique. David reminds the riders of the importance of accuracy and using their voice and body instead of relying on hand.
