I've read differing opinions on carry within US National Parks in various locations. I just read PL111-24 Section 512(b) which appears to make it clear that if you are a legal carry person in your state, or the state in which the federal park is located, its ok to carry. My question is - functionally and on a practical level daily is this what our Federal Park Rangers understand the law to be pertaining to their jurisdiction? Also, does this apply more broadly to places like Kennesaw National Battlefield for example? Thanks. 512(b): Protecting the Right of Individuals To Bear arms in Units of the National Park System and the National Wildlife Refuge System- The Secretary of the Interior shall not promulgate or enforce any regulation that prohibits an individual from possessing a firearm including an assembled or functional firearm in any unit of the National Park System or the National Wildlife Refuge System if-- (1) the individual is not otherwise prohibited by law from possessing the firearm; and (2) the possession of the firearm is in compliance with the law of the State in which the unit of the National Park System or the National Wildlife Refuge System is located.
