Police face west along Route 9, especially after the reservation has closed for the day at dusk. There is a dip in the road which makes it easy for them to hide. They clock in both directions; I was coming eastbound. At the bottom of the hill the speed limit is 50 (I think–it’s hard to remember because MA secondary state highways have NO consistent speed limit) but at the top of the hill, just before the reservation driveway, it drops to 35.
