Southbound Powers Boulavard crests a hill (without visibility problems) at Old Ranch Rd. At this point the posted limit goes from sixty to fifty five, but prevailing speeds, especially at night, are often higher. Motorcycle cops are hiding inbetween the yellow barrels used to prevent people from coliding with the median. Usually the only way to ascertain thier presence is by seeing the top of a helmet poking out above the barrels. This qualifies as unjust enforcement because it is placed immedietly after a drop in the limit, and because the speed limit on this section of road does not reflect the 85th percentile speed or a safe and reasonable speed under perfect conditions.
