Location: Westbound I-80 at Vacaville. Time: 7/30/02 7:00am. On my commute in this morning, I was passed at a very high rate of speed by a Ford Ranger. I was doing about 80-85 mph indicated, he easily 95+. Then another car goes flying by. I'm just figuring that it's kids racing or something like that. Turns out, this second car is an undercover LEO. Pulled the truck over within 2 miles of the first sighting. Dark green, late model Ford Contour/Taraus. No external signs, whatsoever. It had one red light in the windshield, and one rear facing yellow light in the rear window. Very sneaky. I don't know if it was CHP or local police.
