How about getting rid of gun free post office zones.
I am for eliminating all school and federal property gun free zones except where you have to pass through a permanent metal detector for ccw folks. It is silly that I can hike all over THE GREAT SAND DUNES NATIONAL PARK but have to lock my gun in the car to enter the visitor center. My understanding of the federal school law is the 1000 foot zone applies to out of state people. Where I live I still cannot carry on school grounds, except in my car, BUT someone out of state could not drive past the school without breaking the law. Will ask in legal class Thursday night.
Here is how President Trump can do it.
