What a weekend it was, racing with the American Sprint Car Series. It wasn’t our best effort, and it wasn’t our worst, but we did what we set out to do: secure our 2nd consecutive Championship. We’re proud to say we wrapped up the 2025 ASCS Northern Plains Region Championship, to go along with our 2024 ASCS Western Plains Region Championship.
There’s still a lot of racing left this season and more goals we’re chasing, but right now we just want to say thank you. To our amazing partners, this truly doesn’t happen without you. It might sound cliché, but your support makes all the difference.
And of course, a huge thank you to our family and friends who make the unseen sacrifices that allow us to keep doing what we love. We’re grateful for every one of you.

What started as a scheduled weekend off turned into a special opportunity thanks to the generosity of Bob Harr. Bob offered Adam his midget to compete in the “Rick Sheil Back Row Challenge” at I-76 Speedway with the Rocky Mountain Midget Racing Association and Adam brought home the victory, his 4th overall win this season.
We are incredibly appreciative of Bob, Duane, and Greg for their support and the chance to be part of this event.
We’ll be back on track with the Sprint Car in two weeks when the American Sprint Car Series heads to our part of the country.
