Sadly I don't have a picture of it, but when a friend of mine spent a year in texas his host-family had the following text on a sign that hung on their fence:
"One of the three houses in this road is defended by an armed owner.
The house on the right is deserted, and the one to the left is owned by a pacifist family.
Guess where you shouldn't go unauthorized."
Kinda telling it straight.
