Under state law you are fine. Federal law says that you can not carry within 1000 feet of school property. That means the outside edge of the property, not the building. There are several exceptions to this federal law. One of the exceptions is on private property. This won't help you at a firehouse. Another exemption is for those that are licensed by their state. It does not say you actually have to conceal your weapon. You don't say whether you have a KY CCDW. If you do, you would be OK. Without one, you would be in violation of that federal law.
