In Cool, the speed limit drops 5mph to 60mph, then returns to 65 soon thereafter. After the northward bend in the road, the downhill descent begins (65mph zone). Near the bottom of the descent, the speed limit changes to 55mph (well marked "Reduced Speed Ahead"), but then quickly changes to 45mph. MWPD have been seen parked in front of a vacant building, somewhat behind a sign, monitoring westbound traffic. Difficult to see the car before you hit the 45mph area, then it’s very obvious. Other locations can include a side street 1 blk west of the two motels. Make sure to not "sail down the hill"! Observed many times, in the daylight morning hours.
