If you have a CCW, always carry. And let it be known you are not a soft target.
If you have a carry license, always carry. Do not go into any establishment that is a "gun free zone" and let these establishments know why you won't enter their places of business. (Only people who want gun control should be in these establishments.) Actively oppose all efforts to restrict the Second Amendment. Don't pass your rights off to the pro-gun organizations alone. Buy firearms and ammunition. Do your best to make sure that those who want more gun control are not blocking your aim.
