I just bought an OTTB of the track that I found on the canter website. #1 CANTER for the most part its just a service to list horses that the trainers on the track want to sell. This is not an adoption, this is a purchase from the current owner. #2 Most trainers, especially with horses on the track will not let you ride the horse. You will have to trust your judgement on the movement and attitude of the horse in hand. I brought a trainer, who had a better eye with movement, with me to help evaluate the horses I was looking at. #3 I would bring a trainer with you. It will help keep you on task, when I went to the track I saw over 30 horses that were for sale, you need to keep focused because by the end of the day you might fall in love with half of them. #4 Write up a list of must haves, like temperament, conformation, hoof health. Nice to have, like some training out side of racing, let down already..etc This will keep you on task. Take pictures when you go, I noticed that the pictures on the canter site were not true to what the horse really looks like in person...so a horse that you are not sure you like might be much nicer looking in person. The horse that I ended up buying looked awful in the picture but face to face he was wonderful. There will always be something that you will not like about a horse on the track so you need to decide what problem you can over look or not deal with. I knew that I did not want a stall weaver or a cribber, just don't like them. I hope this helps a little bit. Oh last thing, the prices are negotiable, most of the trainers really want to find a good home for their horses so the price they list the horse for most like can be negotiated down.
