Some of the planned 2,000 slot machines are being installed this week.

The tour was not wasted on the commissioners.

“It’s pretty impressive,” said Commissioner Rodney Edmondson. “It’s definitely a high-end entertainment venue.”

“They’ve spared no expense,” said Commissioner Pat Collins. “It’s overwhelming.”

Commissioner Charlie Napier echoed the sentiment of the other two.

“I think it’s grand,” Napier said. “I was kind of overwhelmed by the size of it, especially the gaming part. It’s very impressive.”

Told of the reaction of the commissioners after the tour, Sean Harrison, spokesman for the casino, said: “That’s good. Maybe they’ll be nicer to us.”

Harrison referred to a lawsuit filed by Cherokee County against the U.S. Department of the Interior, alleging that the federal agency didn’t require the tribe to perform necessary environmental assessments before starting construction. The lawsuit also included a motion for an injunction to stop construction.

A federal government attorney has filed a motion to dismiss the case, but there has been no action on the motion.

The commissioners said after the tour and after leaving the site that while they want to be good neighbors, they also must protect county interests. Napier said he didn’t think anything would come of the lawsuit.

Berrey last month told the commissioners that the tribe would pay to upgrade and maintain County Road 110, which the tribe plans to use for heavy trucks making deliveries. Berrey also told the commissioners that the tribe wanted to widen Stateline Road leading to the Tri-State Monument on the casino property.

Cure was asked at the courthouse in Columbus, Kan., if he had made headway on drafting agreements with the tribe about the roads. He said he had been in discussion with David Cooper, the county’s attorney on gambling issues, to determine if the county could get more concessions from the tribe. Cherokee County is reimbursed for Cooper’s fees by Penn National Gaming.

Penn National Gaming plans to build a state-owned casino in Kansas, north of the tribal casino in Oklahoma, initially investing $125 million and investing an additional $100 million over the next several years.

Cure was on hand to make sure that neither the commissioners nor tribal officials discussed any county business during the visit, to ensure that it remained a private meeting rather than a meeting open to the general public. The Kansas open-meetings law defines public meetings as a majority of a quorum of a governmental body that has gathered to discuss matters pertaining to the governmental body. All those elements must be present to constitute a public meeting.

Berrey would not allow a Globe photographer inside the casino, saying that federal regulators were on site to oversee the installation of the slot machines and would not allow photography during the procedure. Two newspaper reporters were allowed along for the tour.
