There really are no laws for open carry as it is granted to you in the Kentucky Constitution, for the most part the majority of the places you cannot OC are places that you cannot normally carry a firearm into anyways. (Court houses, jails, ect. Though schools you can if you have the administrations permission.) As far as OCing daily I do it and I've never had a call placed on me, you just have to have a certain way you present yourself. (Don't dress like a thug, don't carry it in your waistband though that is still 'legal' in KY) I carry a Smith and Wesson SW99 in a Blackhawk Serpa thigh rig, though it probably does help that I still wear my dog tags and every jacket I own has a flag on the right shoulder.
As far as it being on your leg in a traffic stop it's not illegal so long as it doesn't get covered by something as it is still being openly carried on your person (I had to research this as I'm left handed so my rig would be between me and the door), though you still have to be 21 to buy a pistol and carry it.
For the most part people seem to assume that if you're carrying in plain sight and you're respectful and courteous then it really isn't an issue, they may not like it or understand why you do it but contrary to what is shown, most people are reasonable.
As I told the rather nice LEO in Madisonville (even though I didn't have to stop because KY is not a stop and identify state), I carry for three reasons:
1. Because I can, it's a right set to me in two different constitutions and if I don't use my rights I lose them.
2. Because I understand that the police are not there to protect me, sure they'll do it IF they can, but their job is to solve a crime and catch the person responsible, and the only person who is responsible for my life is me.
And finally 3. Because I never know when something might happen. If some little wannabe thug or gangbanger sees that I openly have a firearm, how likely is he to try something with me? (And yes CC guys, it ruins the surprise and if I'm in a building they're going to target me first.) But I still think that people who commit crimes are cowards first and foremost.
Sorry for being so long winded, 2nd amendment rights are something I'm really passionate about. Hope that helps you.
