It is your choice but if they don’t know you have a CONCEALED weapon why disarm yourself?
I think it is a duty to disobey immoral laws.
I usually do ignore the signs - this was a special case/opportunity and I didn't want to make the point while "trespassing" (general charge against those who ignore the signs and get caught with weapons). Besides - in warm weather I usually just leave my shirt out over the weapon and it isn't bulge-free unless I modify the way I carry which makes it less comfortable and a little slower to access.
