Unless they see a sign stating the area is a gun free zone. Then you’re safe.
I told her that sign isn't so much a rule, but a guideline. And winked.
(Disclaimer - in my state the most they can do IF they catch you is ask you to leave. If you put up a fuss or refuse, then it becomes criminal trespass.)
Of course the Capitol has metal detectors, the theater doesn't.
Thanks for the clarification! I'm glad we are in the hands of sensible people.
