We just added a new feature to the site: you can now see when a spot is about to become available. These new markers have a star on them. When you are browsing the map and you see one of these, it means the parking rules for that spot are about to expire, and you'll be able to legally park there very soon (hopefully before anyone else realizes it!)

For example: if the current time is 9:35AM on Tuesday and the rule is No Parking Tuesday and Thursday from 9:00AM to 10:00AM, then this spot will have a star on it indicating that it will be available in 25 minutes. These spots are more likely to be free.
