First, welcome to the forum and welcome to open carrying.
Next, spend some time reading past threads here in the Ohio forum. There's plenty of good info here.
Then, realize that a LEGAL action is never a cause for being charged with inducing panic OR disorderly conduct.
If you don't already have one, get a voice recorder. Have it with you AND recording anytime you leave the house open carrying. Even while alone in your vehicle, even if your handgun is unloaded and stored properly.
If you haven't experienced any personal negative interactions with law enforcement, don't go looking to confront them. Put on your handgun and go about your daily business. If anyone asks you about it, calmly explain to them that open carry is legal in Ohio.
If someone wants to argue with you, don't argue back at them. Some folks just don't/won't get it.
Familiarize yourself with the various firearms laws in the Ohio Revised Code at http://codes.ohio.gov
An open carry group is a good idea. Do you already have some other folks in the area that open carry?
I'm in Logan (Hocking county) and could probably attend events down there. There are some folks in and around Cincinnati that might even attend.
Above all else, have fun and stay safe.
