Mud Drags Driver Registration: Big Sky County State Fair

We will have one day of racing where we will be running a double elimination dual drag mud race. This will be a much faster paced event than in the past as we need to fit into certain time slots this year. Class specs are included below. Some classes might be combined depending on the number of final registrations.

Registration is open for 60 participants. Once these spots are gone, registration will be closed.

Please note the following:

-Driver registration must be completed by July 14th at 12:00am

-Everyone in the pit area is required to have a pit pass. A pit pass gives you access to the pit area as well as access to the fair. Pit passes can be purchased when you complete your driver registration. A pit pass is included with your driver registration.

-There is a zero tolerance policy for drugs/alcohol in the pit area. Coolers will be checked upon arrival. If you or someone in your group are seen with drugs/alcohol in the pits, you will be disqualified and banned from future events.

-Parking in the pit area is more limited than in years past so we ask everyone limit their vehicles to a tow vehicle, trailer and race vehicle.

-No pets are allowed in the pit area
