haven't gotten one yet but it's only a matter of time.
I sometimes ride on the sidewalk if I felt it was too dangerous to ride with traffic,
such as a busy narrow unmaintained street that feeds into a major artery where no one has
any patience and will buzz by you forcing you into a giant pothole or drain gutter.
I've gotten a summons for bringing my bike into the subway but this was in the 80's
and one for a BB gun. same time period, if I did that now, I may be dead.
both times went to court, found guilty, paid the fine. I must say being in front of
a judge and a court is quite an intimidating experience.
good luck.
