Not really pertanat to ace here, other than a story about foundation bred horses. The people posting on this thread might find it interesting to some degree:
A young girl came to our house the last two Sundays in a row, to ride in the arena a little bit. Maybe to pick up a few tips here and there. She had previously just ridden around her house, and pasture. She doesn't really have a background in horses, she just really enjoys them. Last Sunday, she showed up, with just a horse. It could hardly be ridden around the perimeter of the arena. I told her if she came back, she could ride one of ours, but she showed this Sunday with a really really nice looking buckskin gelding on her trailer. Atleast 300 pounds over weight, but you could tell what was under there, and it was foundation all the way. I asked both her, and her dad what the story on the horse was. Neither one of them knew anything about it. They had borrowed it from a family member. The thing ended up riding out real nice, had a ton of handle, and a good set of brakes. They didn't know how long it had been since it was ridden, maybe even a few years. I mouthed it to be about 12 or 13. The thing haunted me all day, so I started making some calls. Turns out its heavy heavy skipper bred. I haven't seen the papers, and doubt they still even exist. He's a finished head horse. He has sold once for $40,000, and once for $14,000. The most recent time he has changed hands was to be turned out on grass, by someone's house, because he was so pretty. The horse is sound in every way, he's just a lawn ornament now. There is no way, that anyone could ever buy him, not at any price. Subsequently he may never be ridden again.
