Question About Street Sweeping Tickets

Hi Neighbors, Recently, we have been getting tickets from the Pittsburgh Parking Authority for street sweeping infractions, even though there is no signage on our street restricting parking on street sweeping days, and we've never previously received tickets over the past eight years. The tickets have also been inconsistent in terms of when they are issued - sometimes on Wednesdays and sometimes on Thursdays, so I'm not even certain when sweeping occurs. The tickets have all been dismissed by the Parking Court, but it's become a real annoyance. I'm just wondering if anyone else in the neighborhood is having the same issue. -- Benjamin Kelley 412-728-1331
