Kirk Stierwalt gave a couple free clinics at Canadian Western Agribition last November( he was sponsored by a feed company to come). He used a white bull calf we were showing to demonstrate with. It was extremely educational to watch him change this calf, in fact , his before and after appearance was very dramatic. In the clinic he only had time to clip one side of the calf entirely. After the second clinic was over, he found our stall in the barn and set up shop again and totally clipped the calf again. He had another crowd watching again. When he was all done I tried to pay him for the work he did and he refused to take anything for it. I thought he did a great job and he also went far beyond the call of duty as he really did not have to come and spend another two hours clipping after his clinics were completed.
In regards to his videos, I think they are well worth the cost. It doesn't take very long to recoup yoru $40 investment, even if you only get one good idea from them. I have them and have lent them to lots of 4-H kids that live close. They always seem to like them.
