I had errands to do today which required being out and about in my vehicle. Our city fathers have seen fit to place traffic signals at most of the intersections on the streets I traveled. As my luck would have it, I spent quite a bit of time waiting for lights to turn green so that I could proceed. During one of those waits, I idly observed the vehicles passing on a particularly busy cross street. After watching dozens, if not hundreds, of cars, trucks, and buses pass by, it suddenly occurred to me that white-walled tires seem to have disappeared. I paid more careful attention at subsequent stops and can report that (at least today), on the possible thousand vehicles to which I paid attention, I did not spot a single one (white wall tires, that is. I did spot the vehicles.)
Sic transit gloria tires.
Tomorrow is also a day.
