Sounds like my horse! I did find his old for-sale ad from about that time last year. I have tried to contact his previous owner but no luck. My best guess is that he was bought by someone who maybe had some issues handling him (he is quite a lot of horse sometimes) and maybe they got hurt or something...the fact that he was gelded last spring adds to that suspicion. Whatever the case, he ended up passing through a few owners very quickly February through June last year, and ended up dumped at a farm in Maryland where no one had time to ride him (or, it appears, even to feed him). He has no medical problems at all and is in general a very sweet, well-mannered boy and bonded with me very quickly after I gained his trust. His only flaw is that he is very cold-backed when mounting and so sometimes I need someone to hold him for me and lead him around a bit after I get on. Other than that (and the usual OTTB attempts at rushing if he can get away with it) I can't find a reason someone wouldn't want him! He is my complete dream horse and I already love him to death.
Workingtrot, there are some pictures of him from the first day I tried him out under his link in my "horses" tab if you want to take a look to see if he looks like the same horse...he is a bright bay, 16 hands, with a hind sock, a tiny star, and a cute head with a long forelock and a bit of a dished profile (unusual as he is a TB). If you don't mind me asking, what state was the barn in which you worked? I know the gal we bought him from picked him up from Maryland, where her friend just wanted to get rid of him. Did they call him Sprite? He seems to respond to it and it is easy, as his show name is Class Sprite. Did you google him just to find out what happened to him?
He knows when you're happy; He knows when you're comfortable; He knows when you're confident; And he always knows when you have carrots.
