I think if he is to run in the BC we'll know soon enough by where he runs next. He's trained on both surfaces. Poly would be easier on his feet if he does have problems. He could have an entire Derby prep run on poly, then do as today and make the BIG run on dirt. He could have come east because the west coast dirt tracks are much harder. The east coast dirt tracks are softer, and we all know how soft CD is.
