I strongly agree with the above but would like to take it a little futher down the road.

You best know the law where you are visiting. Some states do not allow printing, some call a hint of a gun brandishing. My state will not allow a CCW holder to carry at a parade for which a parade permit was issued. At least one state I know of forbids carrying on government owned property.

While carrying concealed, ignornace of the law is not an excuse.
