Right now, visitors can carry a gun in a National Park as long as it is unloaded and stored. These are the rules that many Americans have been following for decades. So, if you hunt in a National Forest and cross into a park, that is how you have proceeded.
This year, the Bush Administration announced its intent to change these rules. It should not surprise anyone to know that the administration is altering the rules without any analysis of how this might affect visitors and wildlife.
