Aye Denburn is a little bit nasty but those pics were taken late afternoon, plenty shoppers about and spotted a couple CCTV cameras in the area, doesnt seem to have deterred the graffiti artists though.
Stew, your harbour ones could fall under the risky location factor depending on what time you end up down that part of town, could get more than you bargained for. Be good to get near the lighthouse. Was up at Lecht today, some amazing scenery, no Z shots though. The g/f was over the moon with a photo opportunity at **** Bridge!
