A holiday card from Greg Biffle and his family landed in a friend’s mailbox just days after the tragic plane crash that took their lives. The photo of Biffle, his wife Cristina, and their kids Ryder and Emma, smiling in front of a Christmas tree, feels especially poignant now. It’s a reminder of how quickly life can change and how much one family meant to the NASCAR community. Seeing this card, knowing what happened, really brings home the impact of their loss. How do you think the racing world will honor their memory? #Sports #Racing #GregBiffle
