Had a unannounced test late last nite. Probably just a couple kids looking for a place to do what kids do. They were likely a little surprised when the lights came on before they got within about 100 yds of the house. I had plenty of time to get up, throw on some shorts, lock and load, and watch the car turn around and leave. This is only the 3rd or 4th time this has occurred in the last 10 years. Warning systems are a good investment.
