We were driving north on I-5 on Sunday just past Salem when I noticed in the distance a white 05+ Mustang on the right shoulder kind of tucked into some bushes. It was a white GT with blue stripes... no other markings. As we got closer I noticed the driver's door was slightly open. As we passed I saw a guy in a uniform and signature sun glasses using a radar gun. Is Oregon SP using unmarked Mustangs now?!?!?
