Hamilton Avenue at Highway 17, Campbell, California.
THis is near the Fry’s Electronics store in Campbell. The city of Campbell prohibits bike riding on sidewalks (Campbell Municipal Code 10.48.120), though I guess this sign means there’s an exception along this portion of Hamilton.
And get a load of Campbell Municipal Code 10.48.170:
The chief of police of the city as well as any member of the police department thereof may impound and retain possession of any bicycle operated, parked or used in violation of any of the provisions of this chapter, and may retain possession of any such bicycle until the license provided for herein is obtained by the owner of the bicycle, criminal proceedings for the violation resulting in the impounding have been terminated and the judgment satisfied, and all charges and expenses incurred by reason of the impounding, including but not limited to storage charges, have been paid by the owner of the bicycle. The police department and members thereof are authorized to store any bicycles impounded in garages or other suitable places and to incur storage charges therefor. Such storage charges shall be paid by the owner of the bicycle.
