I asked my neighbor at 24 Thacher Street why he does not park his cars in the driveway. He said that someone had complained. A representative from the city spoke to him about it. After their discussion the city person said it was OK to park in the street. This all sounds odd. The picture attached shows a empty driveway on 12/31/2017. His vehicles parked in the street are 7WR930, 71BP79, I have pictures f this two cars.and sometimes a green Toyota Camary. If I can't park on the street overnight why should he?.
