Officer sits near exit ramp 12 ( Left side) in complete darkness after curve in highway of I-75 North and clocks radar. Speed Limit is 55 MPH. Village has square mileage of 0.3 miles. Village is between north and southbound lanes of I-75 north of Cincinnati ,and collects revenue from mainly moving violations. Two officers, a Chief and a Assistant Chief in the whole community. Recently got my first violation in this area in moderate nighttime traffic. Incident: all vehicles were traveling within 5 mph of each other. I was third car behind two others in far left lane keeping up with traffic with cars and trucks in middle lane and and left lane obstructing view of Officer’s cruiser. All cars braked when they saw parked cruiser. Pulled over for doing 73 in 55. (Was not doing 73 mph, I had cruise control set and know what speed I was traveling). Was issued speeding ticket. Research of this area shows they liked 71mph on tickets seems now 73 mph is the norm on tickets issued. Be careful!!
