"Grey area"? How so? What is the source of information for the existence of such a policy. What are these "authoritative figures" basing their opinions on? Have they furnished any written support of their opinions. If you are talking about just "rumors" or "guesses" by someone, then you could be told anything. The legal carry of firearms, open or concealed, is not restricted by any agency of the Commonwealth of Ky. in any Ky. state park. Don't you think that if such a policy existed that it would appear on the State Parks website? Go and look; do a search for "guns" and "firearms". The state has no authority to control the legal open carry of firearms except in schools, detention facilities, court facilities and loaded guns in bars. Concealed weapons can not be regulated beyond what is written into the concealed carry law, i.e. KRS 237.110 and KRS 237.115. In some, few instances state parks contain Corp of Engineers controlled property where firearms may be controlled by federal law. Usually, but not always, COE property is limited to near a dam and has signs up. I know of no incident where anyone has been cited or even asked to leave COE property located in a Ky. state park solely because they were carrying a firearm, but I suppose it could happen. Lake Barkley State Park has a trap and clays range. They will even furnish you with shotguns if need be. There are very few places where you can not carry a gun in Ky. I have carried a gun into the State Capitol building on many occasions. I have sat in my State Senator and State Representative's offices while open carrying many times. I've OC'd into the State Police Barracks in Frankfort. Enjoy your visit. We have a wonderful parks system.
