We went to visit some friends in Rayburn country. They have these alarms on the door that they turn on at night. If the door is opened, they make a loud, piercing noise. I was suprised at how well you could hear them all over the house when we would forget to turn them off in the morning.
I asked them where they got them, and they said, "The dollar store."
And to think that I was limiting my purchases there to pencils and greeting cards.

The NRA & TSRA are a bargain; they're much cheaper than the cold, dead hands experience.
