Riding

Are the RS horses ever ridden? By this I mean mainly the broodmares. Most of them seem to be bred 24/7 so due to that they’re not ridden. But what about the freeloaders. For example wasn’t Raven suppose to be a ”family horse” of some kind? Who they could do all kind of things with. Are these horses ridden behind the scenes by someone other? Does Katie ride at all? She has made couple videos where she rode Bo and Annie (I think) but she has a lot of other horses as well and often talks about showing them and riding them but that has yet to happen.
