Do the horses get to bring their own ponies? Or are the ponies assigned ahead of time? I just noticed that most of them were decked out matching the silks of the horse they were ponying.[/QUOTE]
Some use their own stable ponies, the rest are freelance pony riders that work for the trainers. Every pony person knows who they are taking as soon as the entries come out.
