As a business owner, if you could choose between a small sign (that is much more likely to be missed by the general public) and a big sign (what we currently have) that had the same force of law to ban the concealed or open carry of handguns in your store which would you choose?
Same question from the perspective of the law-abiding person?
Frankly, I really like the big signs we have now because they tell me exactly where not to shop and make it much harder to unintentionally violate the law.
