And he was every bit as amazing as I hoped and expected! I went to (watched, not participated in, unfortunately) a clinic in Washington. I know some people find him less awesome than I do, but even going in as a huge fan, I don't think anyone there would argue with what I saw:
1. He's an amazing horse person. Every move he makes is gentle and focused on the horse. He exudes compassion and calm.
2. He's honest and doesn't indulge people who don't deserve it. I've heard people say he's rude at his clinics, but the only
time I heard him sound less than engaged is when a woman in the audience (not a participant) repeatedly asked him irrelevant questions and then tried to argue with him. And even to her, he was respectful. (Example: When the clinic group was working on getting a soft feel at the walk and trot, she interrupted with a question about when it would be useful for a cantering horse to do a "simple lead change in the front and a flying change in the back," if that's even possible)
3. The participants had an awesome time. There were tons of heartfelt thank-yous from the two full classes (50 riders total). And Buck seemed really to care about them and their horses. He knew all their names and made individual comments despite the fact that there was a ton going on all the time.
