FWIW, Del Mar did care about the 17 fatalities in the 2016 summer meet.
The 2017 meet concluded yesterday. Del Mar hired a new track superintendent (I believe he was hired after the 2016 season), the dirt track was completely reworked (i.e., more than just getting the graders out ) to be similar to Santa Anita (yeah, I didn’t do the look-it-up so going from memory).
Field size increased over last year and the absolutely best news was the fatalities were down to 6! Four during racing, one during training and one “sudden death” in the barn area.
I would say a considerable improvement. Goal, I am sure, is zero fatalities so Del Mar and other tracks should not rest on their laurels but to say that tracks don’t care may be an injustice when they do…
