Are they still doing zoom parking court? If so, it's worth fighting as it's about 25 mins of your time. Hopefully you took pics of you parked so you can show the judge. We went to fight one where people had put up no parking signs that morning (vs the two days in advance). Which meant we didn't really have proof (except it was literally directly in front of our house and they ended up putting the sign on our front door so we would have seen it). But still got the ticket knocked down to $15.
