The City of Frederickburg uses a technology called autoChalk to encourage residents and visitors to obey the time-zone parking restrictions in the downtown district. Thus, you will not see parking meters or parking attendents writing tickets, it will just arrive in your mail, if you have stayed in the same parking spot longer than the alloted time. So if you think you might be at a place longer than the time allowed, use the free municipal parking lot on Sophia St. or the nearby parking garage.
