We all know how the US has terror alerts and they change the color every so often...I don't really know what that does as far as affecting people's everyday lives, but we have it and that's good I guess.
Well, over here, we also have our own terror alert system, but it's a little different than the colors. How it works is: On each side of each bridge there are several soldiers stationed and they have a truck with a 50 caliber, plus they each have AK-47s and then some smaller guns just laying around. If the soldiers are sitting up in the truck paying attention to things, maybe even with a guy behind the big gun, then you know something is going on. However, if they're picking their noses with the ends of their guns, laying flat on their backs underneath the truck in the shade, or lounging around just reading the newspaper and drinking tea, then you know there's nothing to worry about that day...and also, you can feel very safe and protected!
And yes, I have actually witnessed ALL of these things!
