Just wanted to encourage people to be extra careful when coming to and from your car.  I was loading my car at 5:50am this morning.  There was a young man across the street that was walking in the opposite direction of my house.  When he heard the car door, he turned around and started running toward me.  Fortunately I was able to get in my house and set the alarm.  This may have been perfectly innocent, but I'd rather warn people for no reason than keep silent and someone get hurt.
