From city of Celina to the Grayson/Collin County Line, roughly 10 miles, all times of day and night, always there. Posted speed limits are 55 to 60 MPH, heavily patrolled by City police and Texas highway patrol. They hide in low ditch or behind trees, lights off at night, and pull anyone over going even a little above speed limit. Outside of this rural 10 mile range the speed limits are 65 and 70 Mph, so it is very easy to miss this reduced speed limit area.
