Skipzoid
It was still there when I passed last week. You can see it on Google Earth, South of the junction A243 / B280. Enter "Malden Rushett" and when the zoom stops, 5 o'clock from the "X" 4 fingers distant.
It is inside the London zone, you do understand.
By motorcycle it is about 30 minutes to central London (Charing Cross)from there. By car it would be significantly longer in traffic.
