I LOVE CLINTON ANDERSON!!! I forgot who originally posted about him, but I think he's the best of all the "natural horsemanship" clincians. He's down to earth, funny, and really knows what he's doing. I don't mean to offend anyone, but I think a lot of Parelli is just smoke and mirrors. Clintons methods are straightforward and easy for both horse and riders to understand. He doesn't put up with anything but respect from his horses but at the same time is very kind and doesn't believe in using harsh or abusive methods to get what he wants. I've seen him at Equine Affaire a few times and his clinics were unbelievable. I was with a non-horsey friend, and even he was blown away by what Clinton managed to do with an ornery horse in an hour and a half. If anyone wants to know more, I highly suggest youtube. He has a series of tips under the channel "DUHorsemanship".John Lyons is awesome too.
