Trap is located about 10 miles south of Dillon, manned by a local constable in a light colored older Ford Taurus. The speed limit drops abruptly from 55 to 45 in a totally unrealistic spot– no change in highway conditions. Signage was not easily observable, if it was even there. Highway has a deep ditch on the right, woods on the left, so watch for any location where a car might park to function as a speed trap. For 63 mph the fine was $183.
