Despite the laws, the summary of Ohio's laws here, O.R.C. 9.68, the Ohio Constitution, and the United States Constitution, you may be stopped, asked for ID, and threatened with charges.
You can and may be charged with inducing panic, disorderly conduct, or anything else, depending on the officer and the county prosecutor (if he/she is involved).
I know - one or more of the above has happened to me, or someone I know, in the past six months - and I have open carried off and on for more than five years.
That said, if you're prepared to deal with those eventualities, then open carry. Be an ambassador to an inquiring public while you are doing so. Dress and act like a "respectable" citizen. If you want to take part in open carry activism, then do so.
Very simply, if you don't want, and are not willing to accept the potential negative repercussions of open carry, then don't do it.
