To whom it may concern,
I received a parking ticket on November 11, and the reason given on the citation was that I was parked in a zone that had been designated for street cleaning.
However, the 11th was Veterans Day, and it was my understanding that street sweeping is not in effect on government holidays. I have never had any problems on other holidays that fell on street cleaning days and am confused as to why I received a ticket. I believe the citation was made in error, and if that is the case, I would like to contest it.
I have never received a parking citation before, and if I had been aware that street sweeping occurred on holidays, I can assure you that my car would not have been in the road crew’s way.
If there are any questions, please feel free to contact me.
