Nothing 4 Nothing

Pink Dots revisited. Today a guy in a "City" vehicle that resembled a riding mower came by and "sanded" the sidewalk where the mysterious pink dots were located. An hour later a "City" pickup truck stopped with 2 men inside, one with a shovel who threw a couple shovelfuls of concrete "sawdust" into a small bucket while other man swept the sidewalk. Neither did their very good jobs...but that is "typical" city workers. About a half hour later a third "City" pickup stopped a man with a clipboard got out and examined the job done. I ask why was taxpayers money spent on this senseless and seemingly useless project? I don't understand why they "sanded" the sidewalk...it wasn't broken oe uneven? There must be other worthwhile projects to spend the money on..but alas...that would make too much sense!
Hot here today to 108, yesterday it was 106.... and it is going to get even hotter.
