Apparently the people who administer Mammoth Cave National Park in Kentucky are upset because we legal gun carriers are clearly going to trap everyone in a cave and shoot them like ducks in a barrel:
Mammoth Cave has previously banned guns from the cave, saying it keeps everyone safe. McDougal says there aren’t many ways to escape once you’re inside on a cave tour.
Does McDougal really think the rule was preventing a mass cave slaughter before? Apparently in his world, mass killers were busy checking the Code of Federal Regulations to check first whether their gun possession would be legal before they go on a killing spree.
Either way, I have to accept that they might be a little challenged in the reading comprehension department, since they are waiting for “guidance from Washington on interpretation of a new law opening national parks and refuges to people with loaded guns.”  All the guidance one needs can be found in the Coburn Amendment itself. It’s one of the simplest laws you’ll ever read:
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 the individual is not otherwise prohibited by law from possessing the firearm and 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.
There’s your guidance. Guns are legal in Mammoth Cave according to Kentucky Law. Now quit your whining and deal with it.
