A couple of years ago I visited Kilmartin with my friend and crawled into
the Dunchraigaig Cairn http://www.themodernantiquarian.com/site/490 for a photo op. As I rolled around, trying to get comfy, I looked up and 2 inches above my nose was the BIGGEST, black slug you have ever seen....shudder! The look on my face, when Vicky took the picture, was a sight to behold!!
