About 100 people held a protest against the casino planned by the Seneca-Cayuga Tribe of Oklahoma.
The No Casino In Grove group wants to stop the tribe's proposed $60 million casino resort.
Organizers say there are already too many casinos in northeast Oklahoma.
The tribe plans to build a 100,000-square-foot casino near the Sailboat Bridge on Grand Lake.
