While driving to Arizona I crossed the Golden Gate Bridge. The toll for cars is $7. There are no toll booths. License plates are photographed and the owner of the vehicle is sent a bill in the mail from the people at bayareafastrak.org. The bill has a black-and-white photo of the rear of the car. I paid on-line with a credit card rather than write a check. I hate writing checks. The webpage says "FasTrak keeps you moving." Crossing the bridge was a moving experience; paying the toll was not. Geotagging shows where my car was photographed.
