Each of the Triple Crown events—the Kentucky Derby, Maryland’s Preakness and the Belmont Stakes in New York—is run on a dirt track. Some in the horse racing industry want to end that tradition and lay down potentially-safer synthetic tracks. But with grandstands increasingly empty, critics say track owners are putting profits over safety. As part of our "Track Tech" series, WEKU’s Matt Laslo looks at the future of track material technology. “Track Tech” is a collaboration between WEKU, Louisville Public Media, and N-P-R’s Innovation Trail.
