I just got my 6 yr old sound OTTB 2 weeks ago, by accident and FREE. On top of that her papers show that she is out of Van Nistlerooy "a 6.4 mil proven sire".
I ended up purchasing a round pen on Craigslist that belonged to a racehorse trainer. When I explained that I was getting a young colt she immediatly started offering up some of her racers that were in pasture. She was explaining how nobody wanted thoroughbreds and trainers with financial or health issues (her case-broken hip from a stud) could not give them away.
Post on Craigslist in Farm and Ranch or Wanted. In TX. We still have many available.
I have pictures of Faith posted.
PS- I am a former race horse owner and we also had a hard time finding good homes for some of our horses. We tended to donate most to the YMCA.
OTTB owners don't know how to find people that want to care for their former racers either.
