"That may not be the technical term for them, but they're mildly distracting, whatever they're called. They reminded me a wee bit of the Fairy Glen in Skye. I shall carry out diligent research on the issue, and update this post in due course. Probably."

Lucky really, because I didn't have many sober days during the eighteen months I was living on Skye.
