In San Francisco, where no automobile parked on the street is immune from glass-smashing thieves, some people have taken to posting signs on car windows announcing that there are no valuables inside.
The hope, of course, is that a thief will read the notice and decide: “Huh. No valuables in this one. I guess I’ll break into some other car.”
When I was in the army me or my girlfriend would rent a car and drive up to Amsterdam to party and score some hash. We learned our lesson the first time – take everything out of your car, leave your glove box open, and leave your doors unlocked otherwise the dope fiends would break out your windows. Those motherfuckers would steal anything that they could grab quick – leave your Zippo lighter in there and it was gone, leave your spare tire and tire tools in there, they were gone. It’s the only city I’ve ever stayed in where you stored your spare tire in your hotel room.
