As a retired Manchester police officer for 25 years some of these location are like shooting fish in a barrel. Most of the guys will give you 10 to 15 MPH over the limit before issuing a ticket, but that depends on traffic conditions, time of day etc. Other locations to watch out for in Manchester are Brown Av down by Tessier St. Especially in summer time (motorcycle units) Also Elm St down by Gas St, and North Elm St by Notre Dame College. Queen City Bridge, and the west bound end of the Norte Dame Bridge. "God speed all travelers"
