The video above (sorry gone from YouTube now) has got to be one of the most amazing riding videos I had seen in some time. As you watch it, look at how relaxed the western rider is when he rides the dressage horse. The dressage rider on the other hand looks more tense riding the western horse and even tries to plow rein the horse for the spins rather than neck rein. I applaud both riders for their showmanship and the video brought tears of shear joy to my eyes.
Update: Sorry but the video has been removed from YouTube. I tried to find it again but no luck.
