Years ago - the San Francisco Police Department spun off its traffic division which became the Department of Parking and Traffic (D.P.T.)
I'll refrain from typing my response when receiving citations for this dedicated group of three-wheeled bureaucrats - (I'll be DPT in SHT) - and simply warn the reader to take extreme caution when navigating a parking space in this City by the Bay. We have a generously sized tow impound facility that gets lots of use - twenty-four /seven.
