Many houses in that upper class neighborhood no doubt have security cameras, so it shouldn't be too hard to identify the vehicle and the people in it.
I've been thinking about getting a security camera for our house. They're so cheap. Or maybe I'll just get a sign stating that we have surveillance cameras without actually getting one, just to act as a deterrent, although crime in my neighborhood is pretty rare. I do worry when we go out of town that someone will break into the garage and steal something, but I worry about a lot of stupid crap. If that were to happen, insurance would cover it so WTF? I'm just a worrywart.
