Bingo, Terry, get off the interstates and drive in town later in the evening on a weekend and you'll eventually find the gestapo check point.
I've been stopped probably 4 times. Always in town (they cant back up interstate traffic for this) and usually after dark on a weekend but not always. I have been stopped mid afternoon but I was also leaving a venue where there was likely to be drinking (boat races). They pick their locals based on the probability of drinking activities and call it a "insurance check stop". BS.
Just for your enlightenment, except for quick trips to some place, I try to avoid the interstates. I prefer the back roads where things are more scenic and laid back. My ticket in Wyoming was during a one day drive from Mountain Home, ID to Colorado Springs, CO, which is an 840-some mile trip. My days of driving trucks seldom ever had me on an interstate. My ticket in the '70's was in Kansas and not on an interstate. Plus, I've had more than my share of nighttime driving in towns and cities of all sizes.
