Or whisper "gun".
Or draw a picture of a gun.
Or carry a sandwich that might look like a bomb.
Or anything that "offends" liberals.

I hope to travel cross country (on a plane) with my gun and take a course in CQC. More gun owners need to do the same.....even if it just means carrying in a state with reciprocity.
Make travel with a gun commonplace and this nonsense will go away.
