Interstate 93 near Exit Number 7
About 1/2 mile before Exit 7 on I-93 Northbound. Expect to see several cruisers as you round a long blind sweeper to the right approaching Exit 7. Speed trap is usually set up on clear, sunny days which is why I suspect aircraft enforcement. NH police usually don’t pull you over unless you are going more than 10 miles over the speed limit, so keep it under 75.
