What would be a good goal/lesson for such an event? I'll start brainstorming and ask you guys for feedback as I'm new to all this. I'd definitly be up for a trip to Lexington if only to get out of town for a day.
I'm not lessening the value of "events", but given your knowledge and experience level one doesn't have to have an event to accomplish something which furthers the rights under law of those who choose to carry a firearm AND educates you on the law and how to deal with those in positions of authority. Gutshot has laid out some specific problems - I say go after those first. An "event" may be the outcome of your efforts, or it may not.
Ohio has an "open records" law, I believe KY's is called FOIA (Freedom of Information Act). Whatever the name, for present and future situations it would behoove you to learn the law and how and with whom it can be applied - in various circumstances.
For instance, why not delve into the apparent policy of requiring insurance for gatherings in LFUCG parks? Just do a records request for their policy, and then ask to see the proof of insurance given them for all the events they've approved? Or, ask the bus system for a copy of their policy regarding guns on buses. Post your proposed communications, or the results of your efforts, here.
By going down this path you will arm yourself better for future interactions, educate yourself, and quite possibly secure appropriate recognition of the law. If an event is necessary, you will have already done your homework.
