Just as you pass the on and off ramps for I-35W N and S, the speed limit drops from 60 to 50. I think its just near the exit for Summit (I just pass through so Im not sure of the exits, Im usually more busy looking for this A-hole than rubbernecking the exit signs lol) You will top a hill and there will be a Camaro Fort Worth police car setting on the breakdown shoulder, or up against the concrete center barrier just a bit furhter up, shotgunning his radar or laser. They are not particular to who they pick off, as I was a victim one morning, traveling with traffic, in a crowd of vehicles, and was pulled over from the crowd who was all doing the same speed. They will patrol for months at a time, nearly every morning. They they will disappear for a month. And without warning, they will be back again. Usually if you dont see him setting in his spot, just wait, you will see him a mile up the road with his fresh kill. Sorry, sorry SOB this one is.
