New town in Southern Arizona that preys on unsuspecting N or S bound drivers on Interstate 19 between Continental Road on the south and Sahuarita Road on the north. Cops sit in median concealed by trees or grade and stop those vehicles traveling at speeds in excess of 65 mph in that posted speed on I-19 is 75 until town limits and reduces to 65. No time for speed adjustment so far as cops are concerned. See speed monitoring and stops during day, but be especially careful after 10 p.m. throughout early morning hours. Be especially careful if entering on access ramp and trying to match speed of vehicles traveling in your direction.
