While driving just north of Great Falls, we were given a speeding ticket in a vacant "work zone". The new pavement was all done, the new lines painted and no one was there working except one guy doing landscaping in the field at the very beginning. The only remnants of a work zone was that they hadn't removed the orange cones from the outside lanes and the 35 mph speed limit sign. I was the only car on the road for miles and inadvertently sped up to 45 when a state trooper comes along from the opposite direction. No warning for out of country tourists from this guy. He gives us a ticket anyway and wouldn't listen to reason. I got the impression from his responses that he had been doing this for a while. I sent a complaint to his captain and received a basic reply of "too bad, so sad, that's the law". We've all seen cops ignore traffic violations and basically give out tickets when they feel like it. This trooper accomplished nothing more than aggravating tourists for the few $ they collected. Lost tourism will cost a lot more than revenue from speeding tickets. I for one, will not be going back to Montana anytime soon.
