It sounded like you were cut off mid-thought.
Welcome to OCDO.
Ohio is, indeed, an open-carry state. It is legal to have an openly carried firearm loaded, with a round in the chamber.
There ARE restrictions on ownership and possession, as well as restrictions on where you can carry. As long as you are not subject to any of those restrictions, you are good to go.
Open carry in Columbus, heck, most of central Ohio seems to be a non-issue. The police and sheriffs are aware of the laws and seem to follow them.
And definitely get that voice recorder.
