As you are coming north on I-17 right before the Kachina/Mountainaire exit, the speed limit changes from 75 to 65. There is a slight incline, and then a slight decline. Highway Patrol loves to sit at the bottom of the decline and catch the people who didn’t slow down to 65. You can’t see the cruisers until after you have crested the hill and by then they have already clocked you. The entire area on I-17 between Kachina/Mountainaire and Flagstaff is patrolled on a regular basis and at some times, quite heavily.
