Doing the short cut from 10 to 49 going west cuttin north at 1:30 am there are miles and miles of flat, flat, flat. Then out of nowhere a steep, very steep bridge appears. Speed limit is 65. One sign, no anticipating warning signs. Focused on bridge I topped it and he was sitting at the bottom trapping. He had me, 65 in a 45, his mistake was being insulting right off the bat. I shifted into my union representative mode to piss him off enough to make a mistake. I was very nice and respectful, overly so, sarcastically so, I was 20 mph over at 65 to 45. NO traffic at all on road. Judging from this officers behavior I think he was waaaay too much on edge. If I am a cop doing a late night stop, I would be relived to see a white haired white old man driving, our demographic do not shoot cops, and he had my record. Not him, he attacked immediately. My guess, he was holding down 2 jobs and running off uppers. Same symptoms I saw in Vietnam. I told his boss all of this, in writing. I think he had a problem and knew it. He ask for my written statements. One question begs to be answered. Why is a cop setting up shop for no reason at 1:30 am on a federal highway during the week in a town with population of 1200. Town has a rep of a speed trap town. Things turned out OK but still leaves a bad taste.
