Sunni is usually pretty tame and when we take him down to the arena, he just stands and looks at us. We have to chase him away. Not Sunday! The minute I unclipped his lead rope, he stood (he is trained to do that) and then took off! He actually enjoyed his romp in the arena! He went around and around and around and around! It was the first time in a while that I've actually seen him enjoy being a horse!
