Warning Sign has been giving owner-rider David Dunsdon some great sport this summer. He could hardly be more versatile, 2nd three times going 1m, then 1m2f and lastly, 1m4f when 2nd in the Amateurs' Derby over the full Classic course. The one-mile run suggests he'll have enough speed for this 7f on testing ground and it's another place chance at least for David.
