Dont use this service!
I used ParkMobile about ten times to pay for parking and received two tickets because of foul-ups with the service. On the most recent occasion I paid more than $5 for parking and received a $20 ticket that was not reversed on appeal. If you dare to use this service BE VERY CAREFUL the tiniest mistake will get you a parking ticket.
