The Dirt’s 3rd annual Proline Lonestar Challenge was a successful event and held a record attendance for the newly renovated and upgraded Thornhill Racing Circuit facility!! With over 300 entries the racing was amazing! Despite rainy weather early on in the week, the newly covered facility was able to hold the record attendance and provide a world class atmosphere for the Lonestar event. The Dirt crew stayed after the race to tear down the LS track and build a BRAND NEW track for the upcoming ROAR fuel off road nationals!!! The new track looks to be challenging and fun! See you all at the NATS!
