Keeneland returning to dirt

[philcski]

All you need to know:

Saratoga, safe dirt surface: 11,000 starters in database, 11 fatalities
Keeneland, polytrack: 9,000 starters, 9 fatalities

Safety is only partly determined by the racetrack. Yes, tracks with poor maintenance are going to have a higher breakdown rate. But there's a much higher correlation to quality of animal. Trainers and vets that willfully send out horses with known infirmities are the biggest issue.
