In reference to the letter by R. R. Miller (April 21), let me add a strong endorsement to the plea for street numbers on buildings.
Building owners know where to find their buildings, so they may never give a thought to the hazard and inconvenience they cause others when no readily visible street numbers are displayed.
The hazard results when the hapless client, customer, speaker or visitor drives along the street looking right and left at a visual clutter searching first to confirm which side of the street is odd and even and then homing in his objective; it's all too easy to hit a car pulling out onto the street or a car which stops for an animal or a pedestrian. It's a big, modern world full of mobile people who would appreciate less hassle.
The rationale for better identification of buildings also holds for street signs which don't require slowing to a near stop street after street. I'm sure that city fathers who think, "Why bother? We all know how to get where we're going" would be amazed to learn of the true number of inconveniences per day that occur.
