Nashua St. near the exit ramp coming off Rt 190 west, police park in a small drive/alley on the corner. If you are coming from Rt 13 down Nashua St and go under the Rt 2 bridge (they sometimes hide under the bridge as well) there is a long turn in the road beginning at Mowhawk Dr. As you go around that turn, you can’t see them until it’s too late. They will be parked on the right.

Coming down Nashua St. from the Rt. 2/190 exchange, it’s pretty easy to spot them parked on the lefthand side of the road.
