Cop just north of the MA border pulling people over Labor Day weekend. Unmarked car, in breakdown lane just as the 3 lanes merge into 2. I haven’t seen much laser usage in NH, so this was a first for me. Cop was a real jerk and threatened to arrest me when I questioned his reading. Had another car pulled over immediately after handing me my ticket. Also be careful as there are often MA and NH cops right at the border turnaround (more obvious location).
