What are your thoughts on competing in the inaugural race at Naval Base Coronado?
“I’m really excited to have the opportunity to race in the first-ever street race at Naval Base Coronado. Street courses are one of my favorite types of tracks, and the venue definitely makes it a special one. We’ve had good speed on the road courses this year, they just haven’t gone our way. If we execute a clean day, it will be a good result for us.”

How meaningful is it to return to the driver’s seat in a one-off event like this, especially with a partner like Jockey at Naval Base Coronado?
“It’s a unique opportunity to drive in the inaugural Truck Series race at Naval Base Coronado. I enjoy getting behind the wheel every once in a while, and I’m thankful to do it with Spire’s help and with a longtime partner like Jockey.
