A Ticket On a Taurus Grows Into Much More - washingtonpost.com
It seems private property still counts for something:

A three-judge panel in Alexandria went even further than Eberth had imagined, ruling that Prince William had no authority to ticket vehicles with expired inspection stickers parked on private -- or public -- property. The ruling by Judge Robert J. Humphreys said state law prohibits only the operation of a vehicle with an expired inspection sticker, casting doubt on whether police anywhere in Virginia can ticket parked vehicles with expired stickers. Because Prince William's code dates to at least 1965, the ruling suggests that the county has been erroneously citing drivers for more than four decades. Since 2000 alone -- the year Eberth got his first of three tickets -- Prince William has written 29,871 citations under Code 13-322, for fines totaling more than $1 million.
