I talked to Mark Burnette, who is training the mustang for the Midwest Mustang Challenge, and he tells me that Mustang Sally is doing very well. He is still having some problems catching her but she is improving.
The thing that he is most excited about is that she seems to be loving their sessions and she enjoys learning new things, also she is retaining what she learns.
I hope to get down there with my camera and get some pictures of her to post here, if the weather ever gets nice.
The weather has been a problem for Mark as well, he has a roof on his large arena but not any walls. The high winds and blowing rains that we have had turned his nice sandy riding area into quicksand and then the cold temps hit which made the wet sand like uneven concrete.
