That is a philosophy I have lived by for years.
Locked, cocked and ready to rock. I have no children in my house and the neighborhood is not what it was 30 years ago.
None the less, I love the home my wife made for my family and will defend us and it against all invaders.
To quote a famous person, "I pity the fool" that messes with my wife if she has to shoot. She has awesome training and experience from her time in the US Army.
I do not look for trouble, but I am prepared for it should it find me.
