The Grafton Police do radar on Westboro Rd which is Route 30. Its by Tufts University. They usually sit at Two Cousins Pizza, but have seen them in different spots up all up and down the road. They are usually there early in the morning. I got stopped one day going to catch the train at the T station. The speed limit is 30 on that road. They usually dont stop you unless you are going 45 or over, the day I got stopped I was going pretty good, but I had a good attitude and apologized to the cop and he gave me just a written warning. But be careful because I heard the Grafton Police like to write tickets.
