The trick is to know, at all times, where you are relative to Gaza, where the rockets come from, says Sderot Fire Chief David Sheetrit. If you're facing north, Gaza is on your left, and you need to hug the eastern side of a building, to keep the structure between you and the rockets. If you get this calculation wrong, you are exposing yourself to a direct hit. Sderot is turning into a city that never sleeps. Fear is everywhere. When you're driving and the siren sounds, get out of the vehicle and run to the nearest shelter or wall. If there is no building, lie down on the road and cover your head. Just don't stay in your car. The main reason is that rocket shrapnel - and every Kassam rocket has ball bearings or bolts in its warhead - can tear through your gas tank and blow up your car. Remember to always have your window slightly open, so that you can hear the Color Red alert and the Kassam shriek.
