A steady stream of dump trucks flowed toward the Mid-America Center Monday to set the stage for the Monster Trucks.
One hundred truckloads of dirt are being dropped on the concrete for this week's Monster Jam.
WOWT Six News wondered where the dirt comes from. We've learned it is stockpiled in town and stored through the year until Monster Jam returns.
Monster Jam features Monster Trucks that can go up in the air more than three stories and jump more than 14 cars.
The event at the MAC begins Thursday and runs through Sunday.
