WEATHER UPDATE 🌦️

We understand there has been a lot of rain recently, and there is more rain in the forecast for this weekend. We are watching the same forecasts as you are. However, as of right now, we fully plan on derbying 100%!

There may be updates throughout the weekend depending on track and grounds conditions, so please continue to watch this page for the latest information.

Let’s be honest, a little mud never hurt a demolition derby. In fact, it wouldn’t be the TBone Memorial Derby without either hot, rain, or both!

So keep heading to Oskaloosa and get ready for a great weekend of crashing cars & honoring great men. We look forward to seeing everyone starting tomorrow morning at 9AM for SSW Tech.

Of course, if severe weather becomes a factor, we will make decisions accordingly and keep everyone informed as soon as we know right on this page. We are working closely with the fairboard on decisions, they have given us the green light to proceed. With that being said, respect the grounds as much as you can. We know things will be soft, wet and muddy!

Until then…
RAIN OR SHINE, WE DERBY! 💜🧡🏁

We are excited to announce the 1st Annual Mahaska County Top Stockman Contest!

This new contest is designed to recognize youth who demonstrate outstanding passion, dedication, animal care, sportsmanship, and stockmanship throughout their project experience. Unlike traditional show ring competitions, this contest is not about winning banners—it is about your commitment to your animals, your knowledge of the industry, and the respect you show to fellow exhibitors.
