I waited until the end of summer and for most of the cars to be gone off the street to call and get the street sweeper to come by and clean the streets. My street has been such a mess all summer. Not once did the street sweeper come by the entire summer. I have now called once for three weeks and left messages at public works. No returned phone calls, no street sweeper. What is our tax money going to when we point out a problem and nothing is done?
