Tell her to keep her 1000 feet from any school unless she has a Colorado concealed carry permit.
Back when I lived in Missouri and we were going through our campaign to get CCW one argument used by the opposition was that we could OC without a permit (except any city that wanted to ban it). One of our guys actually sat down with an electronic map of St Louis and put a 1000 foot circle around every school in the city, it was verually
impossible to drive through the city and not cross multiple "gun free zones".
I seriously doubt any LEO would try to enforce that law in the absence of some other
serious violation as it would have to be a federal LEO or empowered local and they aren't likely to spend the time.
