DOA33:
I'd keep your KY license for now....
While OH does allow unlicensed open carry, the "unlicensed" part has some nasty traps in it, and that doesn't include carrying the weapon concealed.
Namely, you can't
transport a loaded firearm
in your vehicle. It has to be unloaded, and stored someplace you can't easily get to (your trunk is OK if you have one). So, to stay (IMHO) perfectly in line, you have to unload and secure the gun while you (and the gun) are
outside of the vehicle. (Same thing in reverse when you want to put the gun on....)
IMHO/IANAL and all that good stuff, and things might have changed a bit since I looked at it last. (I've been carrying for over 50 years, and got my CHL in 2004. While I still pay attention, I miss things somehow
.
