Alright guys, we've got to clear up some of this misinformation.
You have to inform/notify, IF AND ONLY IF YOU ARE ARMED. Period
There is a TON of misinformation out there, even instructors and police that are armed and insist that you must notify if you have your license, armed or not. That is INCORRECT. Hell, I've had that argument with a cop when I was unarmed. I did not notify, and he tried to write me a ticket for it until I referenced the Ohio Revised Code.
Here's my proof that in Ohio, you do not have to notify unless you are armed.

I'm not saying that its a bad idea to say "Hey I have my CHL, but I'm not armed". But, that isn't required by law!
Mr Ed, I'm glad you were fortunate. I hear way too many stories of people who fail to inform because they didn't know the law, or forgot that they were armed, which seems ridiculous to me.
