Coming off the Lowell Connector the cops hide on the little sides streets on the right. They wait for anyone that will blow thru the yellow as it is turning red at the lights either at the YMCA or the next set at the school. They used to park at the big house on the corner, hiding the cruiser deeper in the parking lot so you can not see it but since that house caught on fire, they are parking on the side streets. They do not usually have their lights on and are pulled back far enough so that you can not see them until you are at the street.
