Tiny, if you want to see proof in the pudding of mules jumping, look up Meredith Hodges. She is the Queen of Mules.
I used to Jump and Event a mule, I was priveledged enough to beable to work on a breeding farm where they bred mules. I got to break and train mules, and I ended up with my own for a while. They are fun - and Meredith was my "go to girl".
Great pics. Thanks for sharing! Almost makes me want another mule, but unfortunately I cannot compete with a mule in recognized HT's.
