Why would you be surprised? C.C. is not turf bred.
I think there are a couple that have been mentioned in this thread that have been tried on turf, but turf racing/breeding is not big business in the U.S.
Many of our well bred turf horses go back to Europe where turf racing is the norm and their bloodlines are popular. We do have some excellent turf sires in the U.S. but European owners and breeders aren’t interested in California Chrome offspring, for good reason.
Perhaps CC’s get will come into their own as three year olds, you never know. I doubt that they will mostly be successful on the turf which for some odd reason you think they will be.
Why is it again that you think CC’s get will be successful on turf? I remember asking you this question before and you didn’t answer.
