Listened to that earlier, very interesting.. i know Edale quite well ( where the rail inspector had the sighting) i park there a couple of times a year and walk a big loop around the top of Kinder scout. Very bleak moorland up on top, highest point in Derbyshire.
I've only got a couple of pics to hand but gives you an idea of the area. Never seem to get many folk right on the top, see edge of the plateau in pic, that's why i like it up there!!
