Ok, here is what happened...
Yes, I was at a Claremore show, and I was sitting in the stands when a Modern ammy stallion class was in the ring. There were two stallions in the ring that were owned by the same person. He was handling one stallion and a friend of his was handling another. I asked how it was possible for a person that did not own the stallion could be showing in ammy. I was told that the ammy rules for shetlands do not state that you have to own or lease the horse you are showing, just that you can not be a professional. And they added that you could not be a women handling a stallion in an ASPC ammy halter class either. I was shocked...but I was told it was in the rule book and had been that way from the beginning. I voiced my opinion that is was a very sexist rule and that was about it.
Now, I have looked in the rule book and I have not been able to find that information. So far the only thing I have found was that you are not allow to show a ASPC stallion in a Ladies driving class. (Still sexist if you as me, but know one has.)
So, I guess from the replies, Jamie will be able to show her stallion in an ammy halter class, but not drive him in the Ladies driving classes...right?
Thanks for the info.
