There's nothing to worry about between the Ollerton roundabout and Clumber on the 614, as far as fixed cameras go. Although I did pass a suspicious Octy VRS estate sat in the lay by on that stretch with the new traffic lights a week ago..
Further south, I think there are those lovely blue and yellow things unfortunately.
I'm 10 mins off the roundabout that joins the 614 with the A1.
As it happens, if you head east off the Thoresby roundabout on the 614, towards Retford, you'll find what appears to be the remnants of a Roman Road. Good for vmax and brake testing. Apparently.
