It is 8.30 in the evening. It is dark and wet, although it has stopped raining for a little while. I'm at the RSPB reserve in Loch Lomond, Scotland, and embark on a journey through the reserve. My way is lined on both sides with candlelights, guiding me in my way through the reserve. It is pitch black and the rain slowly begins to fall again. The atmosphere is stunning. I can barely see something but my ears listen to every sounds that comes out of the darkness around me. Not out of fear. It is an engaged . . .
