Cawdor Quarry? I think you’ll find this is the infamous “Matlock Bando” which was previously on Drone Scene but subsequently removed after increased security measures were put in place.
I see there’s still plenty of fences up (they used to get regularly torn down) but is there still a strong security presence? Wondering if it’s worth another snoop.
And if you want to fly the spot from the comfort of your own home, my Velocidrone map is still around.
