Finally an update. Today I went for a wonderful but short ride on Sora. Sadly it was nearly my first ride since her personality change because after her thinking about rearing or bucking at the same time I lost my nerve a little. We have been working on other things so that I can reinforce good behavior but no riding. Today however she was back to her beautiful, normal self and she carted me around like an angel even though I was a little nervous. I'm sure our next ride will be even better!
I also spent a few hours sculpting and, at the risk of having more posts recently about model horses than real ones, here is what I came up with!
