On Glebe Road, either coming up the hill from Chain Bridge (mornings) or heading down the hill toward Chain Bridge (evenings), cops frequently set up traps. Coming up the hill, they sit on the left berm in the curve; going down they sit on on a little dirt median. Either way, they’re hidden until you’re right up on them, and the speed limit there is 25 — which makes no sense at all, because there are no houses there, and the adjoining residential area has a speed limit of 35!
