Part 3: David O'Connor continues discussing the responsibilities of the rider by asking the group why they might change a horse's speed going into a fence. The riders then introduce themselves and their horse and what level they are working at. David makes some thoughtful observation about tack, including a poorly fitted martingale and bell boots, as well as exploring some of the bitting choices further. Though all of the riders feel they have pretty good cross country horses, there are some issues in the group with one horse being ditchy and others having issues with skinnies and focus.
