THIS is a photo of a 2-HOUR PARKING SIGN IN PALO ALTO CALIFORNIA. They clearly indicate that it is "once per day on this block" . Pasadena SEEMS to think they have this rule as well, or have ticketed me because of it (I think), yet their SIGNS do NOT indicate such a "per block" rule. SHAME ON PASADENA for their INCOMPETENCE and/or CORRUPTION/GREED...in taking advantage of us despite not giving us notification.
