Pretty much any time of day anywhere in Cedarburg police are looking for speeders. There are about four spots on Pioneer Dr that they sit regularly–the medical clinic lot just west Washington Ave on the south side of the road, a trucking drive-way east of Washington Ave on the north side of the street, a large parking lot on the north side of the road just past Hamilton Ave, and north of Pioneer Dr on GreenBay Rd (there they are also watching for rolling stops at the 4 way stop sign). I have seen numerous people pulled over all along Pioneer Dr anywhere between Hwy 181 (76th Street) and I 43.
