At the Bloomberg/MAIG/No More Names event in Cincy on Saturday, we ran into a lot of LEO's that came in for the convention. I talked to around a dozen in total and NONE of them were aware that Ohio was an open carry state, except for one from Arizona.
He thanked us.
As we were leaving the event, four of these visiting LEO's asked us where the beer bash was, thinking we were LEO's. When we corrected them, one of them said to another, and I quote, "You mean I could be open carrying? Why didn't you tell me? Where the gun store at?"
