Barbara Livingston did a blog/photo spread of Rachel. Some nice shots of Rachel with other mares or jumping about and looking at the camera.
No mention of whether they plan to breed her again, and Barbara said in the comments that she didn't ask because that's not what the article was to be about. Someone had asked her about it with a bit of pearl clutching and you just wanna tell people that RA's not their horse and they don't have inside info on her medical status. Stonestreet clearly treats her like a queen. They'll make the decision at some point if they haven't already and they don't need outside angsting to remind them of how beloved she is.
