Speed limit drops at Oklahoma County Line going west on Route 66 from 65 miles per hour to 55 miles per hour almost immediately. Was slowing down to 55 miles per hour but with the officer sitting just below the hill you are coming over you need to start hitting the brakes and/or backing off the excellerator immediately. The officer did not put his lights on but did followed me 4 to 5 miles before lighting me up and stating I was speeding 10 miles over the limit. At the time he stopped me I was obeying the speed limit. I have been told there are 8 full time officers that work in Luther and monitor Highway 66 writing speeding tickets. I will take the Turner Turnpike in the future. I will let all my friends know that a town with so many speedtraps does not deserve individuals business or taxes for shopping in their town.
