I’ve seen them in just about every No U-Turn exit going West to Middletown on 84, coming on from exit 5. It seems they monitor those coming From middletown to Exit 5 more than those going to middletown. Just look ahead during the day for shiny glimmers (they hide in some cut trails in the woods on the median, too) because their cars are reflective off the sun. If it’s night, stay to the right lane. etc, etc. Also, they seem to be out more during the night than during the day.
