Had a stroll in Smallcleugh today, the signposting is ludicrous. Every junction and tunnel has big white lettering or arrows, totally unnecessary. There's also a somewhat ruder bit of graffiti in the Wheel Flats - green spray-paint this time. Removed as much as I could but didn't have anything with me other than elbow grease.
Whoever did this get a mine plan and learn to navigate underground. If you need all this signposting then you probably shouldn't be in a mine in the first place.
