Welcome to OC.
I live in KY and we can also carry openly with no permit which is something that many in other states would love to do.
I CC more than OC, mainly due to my job and such, but I OC on weekends.
I would caution you that, while it does not sound as though you alarmed anyone, there are a few things to keep in mind.
One thing is that when you OC, your firearm should never leave the holster unless needed for self defense. This will lessen the chance of an accidental discharge as well as spooking the ones observing from a distance that may not react well seeing you draw your firearm. Those types are the first ones to call the police and say a man with a gun is at wherever and he just took his gun out of the holster.
That would bring unwanted attention to you for sure.
As much as I understand you wanting to show someone else your firearm, it is best to keep it holstered.
