And the stories started coming:

We park our car across from our house in zone Z on Orange St. It's been parked there everyday since the city zoned the street zone Z. We got ticketed twice this week (October 21st at 11:02 AM and October 25th at 11:06 AM). I attached a picture of our truck where it is parked, and the visible "Z parking zone" sign next to our truck.

We own, live and work in our building on the corner of 8th and Orange. Our upstairs address is 800 N. Orange St., Wilmington, DE 19801 our business address is Poppycock Tattoo, 115 W 8th St., Wilmington, DE 19801. We are annoyed that we have to continually deal with our car getting ticketed. We have to call the number on the back of the ticket, they tell us we need to send a picture to prove we have a sticker, then wait for them to "review the appeal" and in the meantime we get another ticket and have to do the process all over again. We thought the issue was resolved after months of fighting ticket after ticket when we first moved here, and now the problem is back again. We have received at least 20 unjustified tickets since we've lived here. It's extremely frustrating.

NOTE: The City of Wilmington has now addressed this issue
