One of my favorite clinicians is Buck Brannaman. He doesn't have many youtube videos but there is one where he is talking about the best ride he ever saw and another where he talks about an exercise to get your horse more supple and on the hindquarters. I like both of those and for sheer entertainment there's one where he does a bull doctoring contest in California that's fun to watch. I would link them but I'm not sure how.
There's nothing like the Rockies in the springtime... Nothing like the freedom in the air... And there ain't nothing better than draggin calves to the fire and there's nothing like the smell of burning hair. -Brenn Hill
