How old are your kids? If they are younger than high school age, I'd be talking to my neighbors if I were you.
Back when I was in about 3rd-4th grade, my parents got awakened by a loud bang, which was a melon busting on their bedroom window. They went out to find a few more busted on the porch, and 2 sliced sidewalls on my dad's work van. After some what the hell'ing and looking and asking around the next day, they found out that a couple dumbass high-school boys were mad at our neighbors daughter, and hit the wrong house. Of course this was found our because they were bragging about it in some way. Needless to say, when this was all sorted out, their dad's drug their asses over and made them apologize and clean up and pay for everything.
