Aww, they sound like real cuties! I used to help a woman train POA's for the cart. It was a really fun experience, in my opinion. In our down time, she taught me to drive her Belgian gelding who used to pull a carriage in the streets of Philadelphia. Driving seems like so much fun to me!
Wow! That is pretty neat. I had some friends in high school that showed minis in-hand, and my parents had friends who had a stable solely based on driving minis. I always thought it was very cool, and a lot more applicable to "real life" than it may seem, if that makes sense!
