... which means, "on the horse."
While Joe's been 'enjoying' skiing (he still has visible bruises), I've doing doing a little physical therapy. As a part of that, I went out to a local(ish) riding school to try out horseback riding. I have sat up on a horse a few times before in my life — when I lived in Stevensville (9 and younger), the people behind us had a pony and a horse, and the neighbor kids and I would just hop up on one sometimes, and ride around the paddock bareback (we weren't supposed to do it, so don't tell my parents...). And I remember taking a long trail ride in Colorado once, probably also before I was 10.
