Silverado and alot of others....
Silverado's trainer, from what I gathered, really wanted to bring him home for his son Carter. Silverado's family got into a bidding war with someone(?) and they ran the bidding up to 10K or so. The little boy was crying etc...
To be honest I think there were alot of trainers who wanted their horses back. Silverado's folks got media coverage because they were finalist and he went high $$$.
It is really hard when you get so attached to the horse. I know it was for me. Bu is awesome. I work with other people's horses all the time and don't get attached. I got attached to Bu because he's special. A rare find. I am sure alot of trainers felt that way...they weren't your average training horse.
