I splurged and bought RideOn Videos at Twin, and it was not a waste! I can’t embed them, but you can find them on the RideOn website.
Dressage (watch out for Murray’s buck right at C!)
Cross Country (I look like a drunk monkey in this video, but since it represents a significant portion of the first 30 minutes I ever spent in that saddle, I’ll take it — plus, Murray was such a star)
Stadium (sometimes, you’ve just got to double check every fence on course to ensure there are no crocodiles or spare mongooses beneath them)
