Jacqueline in Texas sends in a sign from a local hardware store:
That, right there, is how its done, folks. In amongst all the 30.06 signs that forbid the carrying of arms, here's a store that tells customers, right up front, that they are welcome if they are carrying a firearm. This sign, mind you, is a thousand times more effective than a "no guns" sign. Think about it. A "no guns" sign tells a potential bad guy that he will be the only person in that store with a firearm.
That sign tells the same potential bad guy that he's playing Texas Roulette if he whips out a heater in that hardware store...
That is all.
