The Cat & Fiddle is in Derbyshire/Cheshire and is the main road betweeen Buxton and Macclesfield.
To be honest the road isn't as bad as it's made out to be, but naturally accidents happen when you act like an idiot and don't read the road, and because it attracts a lot of biker attention it will naturally have more accidents.
The Police do make a presence and again it's not that bad, especially the section after the Cat & Fiddle pub into Macclesfied (which is the best part of the road as well), but they do have a Plane that patrols the area although I've never seen it myself.
They are planning on putting Average Speed Camera's up on the road later this year/early next year and (allegedly) these will be linked to ave speed camera's on other roads around it.
