Firstly, it's a big deal to hang out with these guys, I was so fortunate to be able to do that. They are both masters of their craft and art (of which good painting and good horsemanship are both, I believe), have been at it a long time and are sources of infinite wisdom.
They are extremely generous with their knowledge for those who are eager to learn, who have the "try". They may lose that patience when faced with excuses, inattentiveness, lack of "try" and (in Buck's case) abuse of a horse. They would both most likely prefer to be out alone in the rugged country doing what they love to do rather than teaching in an arena or surrounded by other painters. I can't blame them, but I am so very thankful that they both continue to teach and share.
