First and foremost, we are praying for Sam, Brexton, Lennix, Gaye, Tom and Kurt. They stood with us through our own grieving just five months ago, holding our hand at the service and continuing to offer support and love. A loss like this is unimaginable for any family, and our hearts ache for them."Kyle was larger than life—iconic, fiercely competitive and an amazing friend to Greg. They leaned on each other often, not only through racing, but through life and personal challenges as well. Greg and Kyle spent time together in Glamis during the offseasons, enjoying watching their boys together and always looking ahead to the future with excitement and pride."It’s hard to imagine our racing community without Kyle. The impact of this loss will be felt far beyond the racetrack. We love the Busch family and will be here for them in any way they need."
