Southbound side of Callowhill. Speed limit is 40, writing anything above 45. They have been there for ticket blitzes twice this month, and very productive as they work the downhill section of roadway. Went to court and found 24 people also ticketed in same spot that day. Officer was there and "agreed" to lower speed to 45 if we would plead guilty rather than fight it. Lowered fine and no points. Multiple people did the same.
