Working Cow horse class at QH Congress, I think? Horse makes the turn to run the cow back down the long side, rider doesn't...horse realizes he's solo and comes back to his rider...
I can't find that one (but would love to see it), did find one with a riderless race horse, (that wins the race!).
And I love this video: Automatic pole bending horse
The very existence of flamethrowers proves that sometime, somewhere, someone said to themselves, "You know, I want to set those people on fire, but I'm just not close enough to get the job done".
Loved the automatic pole horse. Aren't horses cool?????
