State Police checkpoint for license, registration, and vehicle inspection sticker. Checked cars coming off the I-66, exit 18 ramp that would want to then get on rte 55, John Marshall Hwy. Also checking both ways on John Marshall Hwy. They had parked police cars along these three paths with lights flashing. If you are taking I-66W and exiting at exit 18, you can either a) go straight and catch the ramp back onto I-66W, or b) hang a right on Leeds Manor Road away from the roadblock. Also, there is good visibility from the freeway, such that you can see it ahead of time and not get off the freeway. Sightings on 12/2013, and 2011
