I take photos from my car (yes, at the red light!). I almost always have my camera ready next to me. Usually when I do not have it, I miss nice shots. Sometimes my camera is not ready and by the time I pull it out of my bag, the light turns green and I cannot take the picture. There is something interesting in stopping behind a car with an interesting bumper sticker on it, just by chance. I don't know why but I do not photography them when I am walking in the street.
