If one has a car, and parks it on the street, figuring out which days it has to be moved for street cleaning and then leaves town, because the move-the-car-to-the-other-side-of-the-street-day is the day before you leave or after you return, these little colored notices could be a nasty surprise. These went up yesterday, to say that today and tomorrow, there is going to be a movie shoot utilizing the street space, and you must move your car. If you don’t move your car, well, it will be towed. What a difference a day makes… 24 little hours.
