In August 2017, on being named president of the National Museum of Racing and Hall of Fame, John Hendrickson summarized his vision for expanding the appeal of the 67-year-old Saratoga Springs, N.Y. institution to a simple philosophy. “It’s not just our job to showcase history,” Hendrickson said that day. “We have to reach out and promote the sport. The museum has always done traditional things well, and we want to maintain the prestige of the place, but we have to go out and engage the next generation, which gets information through smart devices.”
