Yes good road although I find it difficult to link in as part of a ride.
The Police HQ does make you feel very wary but, as said, they don't appear to have an active presence on the road. The villages need respecting but the bits inbetween are a good blast.
Open roads and twisty bends, some great riding. A couple of small villages in between to slow you down, other than that its throttle, throttle, throttle. Newby Wisk, the North Yorkshire Police HQ is off this road so take a little more care nearer Northallerton, but i've not seen any police yet.
