Me and BC had a similar situation last turkey season with one of the wardens mentioned here.

Came in when the turkeys were gobbling, asked me and my son where the bait was and wanted to walk the property. We walked around the entire property(small) watching him pick up every small seed or small thing in a field thinking it was bait. After he was satisfied he wanted to know where my buddy was. I told him I dont know to go find him, once he located BC he made him do exactly the same thing and walk around for a hour looking at anything small he could call bait.
