On Friday at Michigan International Speedway, Earnhardt Jr. was asked what was the best part of the celebration the week after his win.
Fan reaction was tops on his list.
"Especially the stuff on YouTube," Earnhardt Jr. said. "It's a bit of an ultimate reward, and it's kind of at the core of why you go out and race.
"To see somebody get that excited and that happy about a result is a hell of a pat on the back."
