Iowa Speedway will play host to the metal legends on June 9, and all proceeds from the event will benefit the Native Fund, the Newton Daily News reported.

The Speedway boasts a capacity of 37,000 people for the event, which is more than double the population of Newton. To put it in simple terms: it’s going to be huge.

Newton establishments, especially places that host overnight guests, are feeling it. The Kampgrounds of America (KOA) campground is completely full for the weekend of the concert.

June Dewar, who works in the office at KOA, said the campground is overflowing and still receiving multiple calls every day about available camping space. She said the campground is prepared for the concert because KOA gets packed at regular Iowa Speedway events. This event is a little different for the city as a whole, though.

“It’s quite an impact,” Dewar said. “We don’t know what to expect, actually. It’s never happened that we’ve had something like this.”

To be overflowing is good for income, Dewar said, but it’s a problem because people coming off the road have no place to stay in the area.

“That makes it really hard because everything — motels, every campground — everything’s full around here,” Dewar said.
