Again: Driving around with the doors unlocked and/or the windows rolled down? Asking for trouble.
I almost always lock the doors. But I admit to leaving the window rolled down, as I like the wind coming through. Things aren't bad in local neighborhoods where I live out west, unlike other places I have visited in the northeast with ghetto elements (Philly, Trenton, Washington, etc.). When back east, I definitely roll up the windows.
