Along 231 just north of the Interstate on the north side of Crawfordsville the speed limit coming south changes from 55 to 45 and there is a small parking area on the east side of the road that is behind a large amount of brush. The police will sit behind the brush where they can not be seen unless you are looking for them. This is a Highly watched spot. I drive by every weeknight and about 50% of the time I see him pulling someone over.
