I'm in southern Michigan too. Around Kalamazoo. Have you heard of Willow Tree Equestrian Center in Bangor? I know a trainer there that knows about speed horses and she does a lot of looking online at horses for sale. She always seems to find really nice deals. It might be worth a shot by trying to contact her to see if she knows of any horses for sale in our area.
