Hmmm, don't know why I looked at this thread. I have no tacky signs on my property--period. Not even a No Trespassing sign. Nobody bothers me. And, I don't think "arming" means you are going to come out ahead. You ever killed anybody? I haven't, and I'd be having quite a debate in my head before I ever pulled a gun out. That's how it should be. Life should not be so cheap.
Nope, I don't have such a sign nor do I strut about proclaiming I have guns (to steal). Guns are not toys. Guns are a messy, final answer. There's no going back once you kill somebody.
I agree with HS. If you are living in a horrible place, move. Affordable or not, move. After all, you are willing to kill for your family, why not go down a bit in the financial part if it means a better place? Just don't move here. We don't need a bunch of paranoid people with bad backs from carrying unbalanced weight.
And yes, I plan on having a wonderful day. I slept well last night. That usually means the day will be good.
